Is anyone having any luck getting there phone fixed? I have recently done the iOS 18.1 update and then my phone camera has stopped working. i don’t appear to be on my own either but burnt seeing any positive posts about apple cooperating? not sure how it can be my fault if their software has caused it? I am out of warranty too

Hey, I'currently working on a Driver (and its App) for iPadOS (USB Device). I think have the right entitlements, as my driver gets installed with the app properly (after accepting it in the settings). It also gets loaded once the device is plugged in and so on. However the Kernel is not using the updated Version after I install a new Version of App and Driver to the iPad (at least most of the times). I'm verifying this by reading out the Logs via Console and the Driver prints its Build number on Start(). Sometimes it works like it should but I found no pattern. As far as I understand the iPad should automatically install the new Version of the Driver with the new App if its Build is different from the current one. I'm incrementing the Build of App and Driver automatically post-build so each build the iPad gets has its own Build number (This also works). Steps to reproduce: Cleaning Xcode Build Folder Unplugging the USB Device from the iPad. Building and Installing a new Version of the Driver and the App via Xcode (making sure the build number has changed) Plugging the USB back into the iPad Reading Console output of the iPad However it works (each time if I: Uninstall the app from the iPad manually or via Devices in Xcode Build and install the App via Xcode Open the Settings App and activate the Driver But uninstalling the App each time is taking a lot of time and manual Steps so I would like to fix this issue. Do you have any Ideas? Thanks, Bjarne

Firstly, I realise that Kexts are deprecated. And for my needs, user-space IOKit from an application might be more than I’ll ever need, but I can’t help ensuring I’ve got all my ducks in a row while I’m designing an app. I noticed in the above Kext deprecation notice that it’s more about specific APIs that are deprecated rather than the kext mechanism itself (no mention of IOKit kernel APIs there). Along with the fact that a reboot would be required and various other policy changes. While reading up on System Extensions and the various newer tools, DriverKit, Endpoint Security etc, I’ve noticed there’s no mention of this “IOKit Driver” target/deliverable in the Xcode template chooser. It looks like, from the requirements, that DriverKit is aimed at hardware manufacturers, with a need to request the DriverKit entitlement for development. With respect to Apple’s internal Kext deprecation roadmap, how safe is it to build a product that relies on using an IOKit Driver and are there any requirements similar to DriverKit? Would a developer need to request an entitlement? If I developed an app using user-space IOKit and, for illustration purposes let’s say I also included an IOKit Driver in the app bundle. If I used the IOKit API, including header file constants only (no digging around in the IORegistryExplorer for non-public keys), as Apple intends them to be used, would this fall foul of any App Store rules that anyone is aware of? Put another way, would making use of an IOKit Driver disqualify my app from being distributed via the App Store, similar to an Endpoint Security extension? As an aside, there are a lot of API in the ES Framework that could be used to build apps that have nothing to do with Endpoint Security. File system related apps for example. It’s a shame there isn’t an enhanced middle ground between FSEvents and Endpoint Security framework.

I've asked this question in Stackoverflow, but no response, so I ask for help in here. I follow this guide Debugging and testing system extensions, and try to debug my dext code. In the Attach the debugger to your system extension, it said After your system extension launches, run the ps command-line tool and note your extension’s process ID. This is the current output for my dext status % systemextensionsctl list 1 extension(s) --- com.apple.system_extension.driver_extension enabled active teamID bundleID (version) name [state] * * K3TDMD9Y6B com.accusys.scsidriver (1.0/1) com.accusys.scsidriver [activated enabled] and I used the ps command but nothing happen, I can not get my extension’s process ID. ps aux | grep com.accusys.scsidriver or ps -ef | grep com.accusys.scsidriver How to do that? Any suggestion is appreciated.

I am trying to open the CommunicationControl class IOUSBHostInterface in my USB driver, but it only seems to open on iPad Airs and not iPad Pros. I'm calling ivars->interruptInterface->Open(this, 0, NULL); After retrieving the interruptInterface from the device's InterfaceIterator. I try and open this, but on iPad Pros it returns kIOReturnNotOpen. I've tried closing and reopening the IOUSBHostDevice, closing and reopening the Interface, AbortDeviceRequests before opening, etc. but it just seems to work on iPad Air and not iPad Pro. I've tried on both iPadOS 17.6.1 and 18.2 Has anyone else seen this?

Hi there, My M1 MacBook Pro recently automatically updated to macOS Sequoia 15.2 Beta, and since then, my LaCie 2big Dock 20TB Hard Drive has not been reading and has been giving me 'Unreadable Volumes'. My LaCie is only a month old and has not moved from its location since I set it up. I have 'run' First Aid on the drive on Disk Utility and it checks out. Is anyone else experiencing this issue and is there a workaround to get it functioning properly again?

I have a driver project where I'm opening and closing a connection to a custom driver. If I do what I think I need to be doing to unmap the memory, when I try to open the service again, it fails. If I skip the step where I do that unmapping, the service opens successfully. If I call unmap() before trying to call openConnection() again, it will fail with a -308 error return code. If I skip that call to unmap(), it works and I'm able to communicate with my device. Here's the code where I open the service: public func openConnection() throws { guard !isOpen else { return } // Open device var connection: io_connect_t = IO_OBJECT_NULL var result = IOServiceOpen(device, mach_task_self_, 0, &connection) if result != kIOReturnSuccess { NSLog("Failed opening device with error: 0x%08x.\n", result); throw NSError.cdc_kernelReturnErrorWithError(result) } defer { IOConnectRelease(connection) } if device == IO_OBJECT_NULL || connection == IO_OBJECT_NULL { throw NSError.cdc_kernelReturnErrorWithError(result) } let receiveDataMappedMemory = ClientDriverMappedMemory(connection: connection, memoryType: MappedMemoryType_ReceiveDataBuffer) try receiveDataMappedMemory.map() let transmitDataMappedMemory = ClientDriverMappedMemory(connection: connection, memoryType: MappedMemoryType_TransmitDataBuffer) try transmitDataMappedMemory.map() // Setup async notification IONotificationPortSetDispatchQueue(dataReceivedPort, dataReceivedQueue) let callbackPort = IONotificationPortGetMachPort(dataReceivedPort) let input = DataStruct(foo: 0, bar: 0) var output = DataStruct(foo: 0, bar: 0) var outputSize = MemoryLayout<DataStruct>.size // Trampoline to C function because I don't quite know how to make this work in Swift result = setupCallback(self, connection, callbackPort, input, &output, &outputSize) if result != kIOReturnSuccess { NSLog("Error registering async callback with driver: \(result)"); throw NSError.cdc_kernelReturnErrorWithError(result) } self.connection = connection self.receivedDataMappedMemory = receiveDataMappedMemory self.transmitDataMappedMemory = transmitDataMappedMemory } map() and unmap() functions: - (BOOL)mapWithError:(NSError **)error { error = error ?: &(NSError * __autoreleasing){ nil }; kern_return_t result = IOConnectMapMemory64(self.connection, self.memoryType, mach_task_self(), &_address, &_size, kIOMapAnywhere); if (result != kIOReturnSuccess) { *error = [NSError cdc_kernelReturnErrorWithError:result]; return NO; } self.mapped = YES; return YES; } - (BOOL)unmapWithError:(NSError **)error { error = error ?: &(NSError * __autoreleasing){ nil }; kern_return_t result = IOConnectUnmapMemory64(self.connection, self.memoryType, mach_task_self(), _address); if (result != kIOReturnSuccess) { *error = [NSError cdc_kernelReturnErrorWithError:result]; return NO; } self.mapped = NO; return YES; } Any insights? What all should I be doing to close the service? Why would the unmapping create this issue or what else could the -308 error be indicated has gone wrong?

Hi, I’m developing my own Pcie Ethernet driverkit. My Pcie Ethernet card connect on Razor Core X and connect to MacBook via thunderbolt 3. The Problem: Click Driver application and send activate system extension request, then go to System setting -> Privacy & Security, in Extension section ->click “allow” , the peripherals malfunction immediately after "allow" clicked and type in the password.I can't control all peripherals devices like touchpad, keyboard and all of thunderbolt ports. However, it can regain functionality after plugging and unplugging the device. results I expected: User approve Driver Extensions enable and all peripherals work normally and Ethernet Card works. Has anyone encountered this problem? maybe something wrong in "OSSystemExtensionRequestDelegate" but I have no idea how to fix it Please Help. My Xcode version is Version 15.3 (15E204a). Thanks

I'm tryng to develop a software that can connect an iPhone to a HMI Box in order to use CarPlay and test an app for CarPlay. Since the starting point is to ask the device, i.e. the iPhone, if it supports CarPlay, I have to write a USB Vendor-Specific Request that the accessory send to know for this capability. I would like to know what are the specific parameters to include in the control transfer request from accessory to device, especially: bRequest, wValue, wIndex. I've studied the whole Accessory Interface Specification Carplay Addendum, but i couldn't find anything. Thanks in advance for your support.

I am attempting to build a package for distribution. It is not clear how to fix the profile. Can someone point me some documentation that may help me resolve this? Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile.

Hello, We have noted that our USB-C accessory now supplies power and data after a role-switch when it previously would initialize with supplying power to the iOS device, then move to just transferring data to the iOS device after a role-switch. The charging+data behavior is only seen when the accessory is connected to a USB-C based iOS device running iOS 18. Are there some updates in iOS 18 that would cause this behavior? We noted that the expected case occurs with USB-C devices running on the earlier versions (iOS 17 and below).

Hi, I am trying to develop MacOS application which will be connecting to USB devices and should be available in AppStore. So it must be Sandbox and probably I've to use permission com.apple.security.device.usb. I've following requirements: I need to detect USB devices with file system I need to have ability to upload & download files from this device I need to read device serial number I wonder if I can use IOKit for this and it will be compliant with AppStore rules or not?

I have been working on a multi-platform multi-touch HID-standard digitizer clickpad device. The device uses Bluetooth Low Energy (BLE) as its connectivity transport and advertises HID over GATT. To date, I have the device working successfully on Windows 11 as a multi-touch, gesture-capable click pad with no custom driver or app on Windows. However, I have been having difficulty getting macOS to recognize and react to it as a HID-standard multi-touch click pad digitizer with either the standard Apple HID driver (AppleUserHIDEventDriver) or with a custom-coded driver extension (DEXT) modeled, based on the DTS stylus example and looking at the IOHIDFamily open source driver(s). The trackpad works with full-gesture support on Windows 11 and the descriptors seem to be compliant with the R23 Accessory Guidelines document, §15. With the standard, matching Apple AppleUserHIDEventDriver HID driver, when enumerating using stock-standard HID mouse descriptors, the device works fine on macOS 14.7 "Sonoma" as a relative pointer device with scroll wheel capability (two finger swipe generates a HID scroll report) and a single button. With the standard, matching Apple AppleUserHIDEventDriver HID driver, when enumerating using stock-standard HID digitizer click/touch pad descriptors (those same descriptors used successfully on Windows 11), the device does nothing. No button, no cursor, no gestures, nothing. Looking at ioreg -filtb, all of the key/value pairs for the driver match look correct. Because, even with the Apple open source IOHIDFamily drivers noted above, we could get little visibility into what might be going wrong, I wrote a custom DriverKit/HIDDriverKit driver extension (DEXT) (as noted above, based on the DTS HID stylus example and the open source IOHIDEventDriver. With that custom driver, I can get a single button click from the click pad to work by dispatching button events to dispatchRelativePointerEvent; however, when parsing, processing, and dispatching HID digitizer touch finger (that is, transducer) events via IOUserHIDEventService::dispatchDigitizerTouchEvent, nothing happens. If I log with: % sudo log stream --info --debug --predicate '(subsystem == "com.apple.iohid")' either using the standard AppleUserHIDEventDriver driver or our custom driver, we can see that our input events are tickling the IOHIDNXEventTranslatorSessionFilter HID event filter, so we know HID events are getting from the device into the macOS HID stack. This was further confirmed with the DTS Bluetooth PacketLogger app. Based on these events flowing in and hitting IOHIDNXEventTranslatorSessionFilter, using the standard AppleUserHIDEventDriver driver or our custom driver, clicks or click pad activity will either wake the display or system from sleep and activity will keep the display or system from going to sleep. In short, whether with the stock driver or our custom driver, HID input reports come in over Bluetooth and get processed successfully; however, nothing happens—no pointer movement or gesture recognition. STEPS TO REPRODUCE For the standard AppleUserHIDEventDriver: Pair the device with macOS 14.7 "Sonoma" using the Bluetooth menu. Confirm that it is paired / bonded / connected in the Bluetooth menu. Attempt to click or move one or more fingers on the touchpad surface. Nothing happens. For the our custom driver: Pair the device with macOS 14.7 "Sonoma" using the Bluetooth menu. Confirm that it is paired / bonded / connected in the Bluetooth menu. Attempt to click or move one or more fingers on the touchpad surface. Clicks are correctly registered. With transducer movement, regardless of the number of fingers, nothing happens.

I am trying to add a few properties to an IOUSBHostDevice but the SetProperties is returning kIOReturnUnsupported. The reason I am trying to modify the IOUSBHostDevice's properties is so we can support a MacBook Air SuperDrive when it is attached to our docking station devices. The MacBook Air SuperDrive needs a high powered port to run and this driver will help the OS realize that our dock can support it. I see that the documentation for SetProperties says: The default implementation of this method returns kIOReturnUnsupported. You can override this method and use it to modify the set of properties and values as needed. The changes you make apply only to the current service. Do I need to override IOUSBHostDevice? This is my current Start implementation (you can also see if in the Xcode project): kern_return_t IMPL(MyUserUSBHostDriver, Start) { kern_return_t ret = kIOReturnSuccess; OSDictionary * prop = NULL; OSDictionary * mergeProperties = NULL; bool success = true; os_log(OS_LOG_DEFAULT, "&gt; %s", __FUNCTION__); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); ret = Start(provider, SUPERDISPATCH); __Require(kIOReturnSuccess == ret, Exit); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); ivars-&gt;host = OSDynamicCast(IOUSBHostDevice, provider); __Require_Action(NULL != ivars-&gt;host, Exit, ret = kIOReturnNoDevice); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); ret = ivars-&gt;host-&gt;Open(this, 0, 0); __Require(kIOReturnSuccess == ret, Exit); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); ret = CopyProperties(&amp;prop); __Require(kIOReturnSuccess == ret, Exit); __Require_Action(NULL != prop, Exit, ret = kIOReturnError); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); mergeProperties = OSDynamicCast(OSDictionary, prop-&gt;getObject("IOProviderMergeProperties")); mergeProperties-&gt;retain(); __Require_Action(NULL != mergeProperties, Exit, ret = kIOReturnError); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); OSSafeReleaseNULL(prop); ret = ivars-&gt;host-&gt;CopyProperties(&amp;prop); __Require(kIOReturnSuccess == ret, Exit); __Require_Action(NULL != prop, Exit, ret = kIOReturnError); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); os_log(OS_LOG_DEFAULT, "%s : %s", "USB Product Name", ((OSString *) prop-&gt;getObject("USB Product Name"))-&gt;getCStringNoCopy()); os_log(OS_LOG_DEFAULT, "%s : %s", "USB Vendor Name", ((OSString *) prop-&gt;getObject("USB Vendor Name"))-&gt;getCStringNoCopy()); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); success = prop-&gt;merge(mergeProperties); __Require_Action(success, Exit, ret = kIOReturnError); os_log(OS_LOG_DEFAULT, "%s:%d", __FUNCTION__, __LINE__); ret = ivars-&gt;host-&gt;SetProperties(prop); // this is no working __Require(kIOReturnSuccess == ret, Exit); Exit: OSSafeReleaseNULL(mergeProperties); OSSafeReleaseNULL(prop); os_log(OS_LOG_DEFAULT, "err ref %d", kIOReturnUnsupported); os_log(OS_LOG_DEFAULT, "&lt; %s %d", __FUNCTION__, ret); return ret; }

Hello, Apple developers. I have joined the MFi certification program. My Accessory to use USB HID IAP2 communication protocol and IOS devices connected, but in the first step, the Accessory to send the following data (0 XFF, 0 x55, 0 x02, 0 x00 to 0 xee, 0 x10) for IOS devices, but the IOS devices have no response, this is probably the reason why?

Hello Currently, we are developing an application that collects measurement data from devices via USB port but we have some problems regarding input buffer size that might reduce the reading speed. The data size is quite big (~1.5 million bytes). For every read action, the app will check the available size in the input buffer by command: ioctl(serialPort.hHandle, FIONREAD, readBuffSize) Then that size will be passed as the desired size for the read command. Between read actions, there will be a short sleep (1 - 3 ms). Please confirm some points below: Regardless of the size of the measure data, the available size will only be up to 1020 bytes, is it expected? Is the above size OS defined or driver defined? Could we increase it? As we checked, there were some missing bytes between the measure data and the actual read data. Is there any chance that the data in the input buffer be overwritten while the read thread is in sleep? Any recommended technique that can increase reading speed while still maintaining the integrity of the data? Tested OS: Sonoma 14.5

Since updating to 18.0 & 18.1 I’ve have issues with CarPlay connected via usb, phone calls specifically where people would say I sound distant and robotic distortion. Tried other vehicles same issue new usb same issue, tried all recommendations with no success some one who refused to update theirs worked well without any issues I’m currently facing. Any suggestions or there gonna be an update that addresses this issue ?
