I've added my Vendor ID to the appropriate entitlement files but my binary fails validation when trying to upload it to the store for distribution. The embeded.mobileprovision file in the generated archive shows an asterisk instead of my approved Vendor ID. How can I make sure the embedded provisioning file has my Vendor ID?

Hi. I am new to ios development and I am using swift to try to develop a sample app to connect a Canon camera to an iphone via a usb cable and I want to use the ImageCaptureCore framework to do this (that is I want to use the USB PTP). Although I see the documentation on the Apple site, I am still unsure where to begin. Is there any tutorials, etc. about where I can get started with this? I was able to find a couple of code snipets and piece together something with ICDeviceBrowser but when I load the program onto my iphone and connect the camera via usb, I am not able to detect any camera. So ideally I am looking for some sort of tutorial that goes through how to do this or if not, what do I have to do to at least be able to detect the camera from the iphone?

Hi, does anyone know if IOUSBDeviceInterface187 and IOUSBInterfaceInterface190 interfaces will be available on application level next years and there is no any deprecation plans ? Common Recommendations are to use USBDriverKit, but is there a real need to complicate USB communication in this way?

The link is as follows: app store: monitor+ I have checked the header file for USB in the IOKit framework of macOS, but it does not exist in iOS. Is it necessary to collaborate with Apple to implement functions similar to monitor+(PTP control camera)?

I am currently developing an USB HID Device, specifically a type of Joystick. However it seems that any attempt of getting a joystick to work on Mac do not work. My prototype works perfectly on Windows, being recognised as such and receiving all data. On MacOS, the Joystick is not recognised as a Joystick though, and the OS does not seem to receiver any Input from it whatsoever. I have translated my code to use both Mouse and Keyboard, both work perfectly. I have also tried to have the Joystick identify as a Gamepad, but again, it works on Windows and is not recognised on Mac (is not recognised as a Gamepad). Are there any specific restrictions to HID devices on MacOS? Apple developer only seems to describe specifics from a software standpoint, not from the standpoint of someone developing hardware. And even then it only seems to describe very specific HID devices, such as mouse, keyboard or a stylus. Please also keep in mind that I don't have much experience developing MacOS applications.

When the product of USB drive we made connected to iPhone 15, what should we set for TransportComponentName? Should we set ‘USB Connector’ for TransportComponentName? The default value is 'Lightning Connector' before. But how about the Type-C port of iPhone 15 now?

I'm working on hardware that communicates wireless and wired with mobile systems. Anything non-i[Pad]OS we can connect via USB and achieve great bandwidth, in situations where this is necessary. Since i[pad]OS does not support FTDI class compliant devices through USB (and also omits the IOUSB framework), I wonder whether we have a way to "work around" this, e.g. how about (ab)using another protocol that i[pad]OS allows? Concretely, would you think it's possible to tunnel our serial data stream via USBHID?

I am attempting to communicate over serial with a USB-C device and an M-Series iPad. I have proven the device to communicate as expected (baud rate, parity, etc) via a Swift app on Mac using a third party library (IOKit) that utilizes the "AppleUSBACM (v5.0.0)" driver on macOS. I am looking to recreate this communication via iPadOS and a custom DriverKit driver that provides this same interface. There is not an example from Apple for serial communication and DriverKit but there is a couple for communicating from an app to the dext, and for other networking examples. There are also other mentions in WWDC videos but they are incomplete and do not provide the needed structure. Communicating between a driver extension and a client app Connecting a network driver Bring your driver to iPad with DriverKit System Extensions and DriverKit My question revolves around architecture and how to set up a driver for these needs. I have gotten the examples to run and understand what is needed for entitlements and other local signing needs. But what I don't understand is if you need a basic setup similar to the "Communicating between a driver extension and a client app" where your base driver subclasses IOService and has two arms. One that subclasses IOUserclient and allows communication between the dext and your Swift app. And another arm that subclasses IOUserSerial or IOUserUSBSerial. I assume then that these two share buffers of memory set up by the base class that allows communication between the two. I have had little luck getting IOUserUSBSerial to compile and have made more progress on IOUserSerial. But when running that and with the supposed idVendor plist entry I am not getting that part of the dext to start or recognize when the USB device is plugged in. Long story short, I'm looking for a basic architecture or example reference to explain serial communication in DriverKit.

Hello there. I am working on a project to control iPhone camera. Using Bluetooth I can take pictures using Vol+ Command. Just wondering, is it possible to do the same over USB? Thanks in advance. Regards.

Hello! I'm trying to get data (like audio) stream from custom vendor usb device with bulk endpoint. When I use AsyncIO in cycle some data was lost. And I saw that AsyncIOBundled can help me with this issue. I've trying to use it: Create memory buffers for (int i = 0; i < DEFAULT_BUF_NUMBER; i++) { kern_return_t ret = IOBufferMemoryDescriptor::Create( kIOMemoryDirectionInOut, DEFAULT_BUF_LENGTH, 0, &ivars->buffers[i] ); } Create MemoryDescriptorRing and set MemoryDescriptor for each index kern_return_t MyDriver::SetupRingBuffer(IOMemoryDescriptor** memoryDescriptors, uint16_t length) { kern_return_t ret = kIOReturnSuccess; ret = ivars->inPipe->CreateMemoryDescriptorRing(length); if (ret != kIOReturnSuccess) { IOLog("CreateMemoryDescriptorRing failed %s", StringFromReturn(ret)); return ret; } for (int i = 0; i < length; i++) { ret = ivars->inPipe->SetMemoryDescriptor(memoryDescriptors[i], i); if (ret != kIOReturnSuccess) { IOLog("SetMemoryDescriptor failed %s", StringFromReturn(ret)); break; } } return ret; } Create completion Run AsyncIOBundled for only 1 index ret = ivars->inPipe->AsyncIOBundled( i, 1, &transferAccepted, (const unsigned int *)&ivars->dataBufferLengthArray, DEFAULT_BUF_NUMBER, ivars->readBundledCompletion, 0 ); In completion i'm always get the error 0xe0005000 (UNDEFINED) But if I use AsyncIO with same buffer - it's success. What am I doing wrong? There are no differences btw AsyncIOBundled and AsyncIO requests in wireshark

I am using a Silicon labs CP2102 chip. I have configured a custom USB VID and PID on the chip, and want to create a MacOs driver (or rather map this custom VID/PID to an existing driver) to make it accessible as a USB serial device from my Mac. Preferably I'd like to map my device to the com.apple.DriverKit-AppleUSBSLCOM.dext driver, but I think the generic USB serial driver (com.apple.DriverKit-AppleUSBSerial.dext) should work too. Silabs also has their own driver (com.silabs.cp210x.dext, downloadable from their web page), if for some reason it is easier to map to that than to one of the native drivers that could also work. Based on https://developer.apple.com/documentation/kernel/implementing_drivers_system_extensions_and_kexts#3616855 and https://developer.apple.com/documentation/driverkit/creating_a_driver_using_the_driverkit_sdk it should be possible to create a codeless dext, which just inherits from e.g. IOUserUSBSerial. I've tried both creating just a DriverKit driver and putting it under /Library/DriverExtensions/ and creating a (default) app and adding a DriverKit driver to it, and putting the app in my /Applications/ folder, but neither works for me. My driver implementation is just this: #include <USBSerialDriverKit/IOUserUSBSerial.iig> class MyDriver: public IOUserUSBSerial { }; and my IOKitPersonalities looks like this: <key>IOKitPersonalities</key> <dict> <key>MyDriver</key> <dict> <key>CFBundleIdentifier</key> <string>com.mydriver.MyDriverApp.MyDriver</string> <key>IOClass</key> <string>IOUserUSBSerial</string> <key>IOMatchCategory</key> <string>com.mydriver.MyDriverApp.MyDriver</string> <key>IOProviderClass</key> <string>IOUSBHostInterface</string> <key>IOUserClass</key> <string>MyDriver</string> <key>IOUserServerName</key> <string>com.mydriver.MyDriverApp.MyDriver</string> <key>bConfigurationValue</key> <integer>1</integer> <key>bInterfaceNumber</key> <integer>0</integer> <key>idProduct</key> <integer>(my custom PID, decimal value)</integer> <key>idVendor</key> <integer>(my custom VID, decimal value)</integer> </dict> </dict> I've disabled SIP and enabled developer mode (systemextensionsctl developer on), though I'm not sure if it's needed. I've scanned through the system logs and looked at the ioreg output. When I connect a CP2102 chip with default VID and PID, I can see that it maps to the native com.apple.DriverKit-AppleUSBSLCOM.dext driver. When I connect the same chip with my custom VID and PID, I don't see any trace of my driver being used. I can see it in the System Information app, but it doesn't map to my driver. I'm currently suspecting it is an Entitlements issue. In my app I have an Entitlements file, where I've added DriverKit USB Transport and DriverKit Serial Family. Do I need something like this for the driver target? There is no default Entitlements file there, but maybe I should create one? Or is there something else I'm missing? I've also noted one odd thing: When I install my app I can see a system log entry, complaining that "package type not SYSX" (for my driver). But I don't think it should be a SYSX package? It's currently specified as a DEXT package.

I have a virtual device, which is redirected to Mac from Windows OS. However, In MacOS, it does not recognized as a HID device even it has only one HID interface. The device name is Virtual Fido, it more likes to be identified as an audio device. Could any one help check?

Before iPhone 15, the lighting interfaces required communication with external devices through mfi authentication,But there is no evidence to suggest that the USB-C interface needs to add an MFi authentication chip for authentication detection. Is there a way to use USB-C to detect external devices and communicate with each other in the app now, so that I can create my app and communicate with hardware devices

I have two USB cameras, they both recognize the camera properly under windows, but on macos there is one that recognizes only the USB, but not the camera. Would like to ask if there is any solution idea or the underlying code reference. thank you.

this is a repost with more appropriate tags. The original is here: https://developer.apple.com/forums/thread/744268 Can anyone advise, or give example of, communicating large (>128 byte) incoming buffers from a dext to a user-space app? My specific situation is interrupt reads from a USB device. These return reports which are too large to fit into the asyncData field of an AsyncCompletion call. Apple's CommunicatingBetweenADriverKitExtensionAndAClientApp sample shows examples of returning a "large" struct, but the example is synchronous. The asynchronous example returns data by copying into a IOUserClientAsyncArgumentsArray, which isn't very big. I can allocate a single buffer larger than 4K in user space, and communicate that buffer to my driver as an IOMemoryDescriptor when I set up my async callback. The driver retains the descriptor, maps it into its memory space and can thus write into it when the hardware returns interrupt data. The driver then calls AsyncCompletion, which will cause my user-side callback to be called, so the user side software knows that there's new data available in the previously allocated buffer. That's fine, it works, but there are data race problems - since USB interrupt reads complete whenever the hardware has provided data, incoming completions happen at unpredictable times, so the shared buffer contents could change while the user side code is examining them. Is there an example somewhere of how to deal with this? Can I allocate memory on the driver side on demand, create an IOMemoryDescriptor for it and return that descriptor packed inside the asyncData? If so, how does the driver know when it can relinquish that memory? I have a feeling there's something here I just don't understand...

I was trying to hide some external drives from desktop, I know I can do it from finder preferences, but it will hide all my external drives from desktop. I want drive A, B, C to be visible on desktop but don't want drive D to be visible. Some website suggest this solution: sudo SetFile -a V /Volumes/"Drive Name" but it says I need command line tools, since I was in terminal, and prompt come from MacOS itself, I stared installation. But what are this tools actually is it sahe to install it? And why this tool taking 2.35GB of storage just to hide one icon from desktop?

Hello, We have a device that acts as a ***** device and communicates with a master over data sent over a USB serial port over a wired connection. We are trying to develop an Application on iOS that will enable us to use the USB connection between iPhone and our device. Kindly suggest to us what is the way to achieve this. A few searches let us know that Apple's MFi program needs to be enrolled. Please let us know how this works and where could we find process for the same. I thank you in advance! Makarand

I have a custom HID USB device that I can control on Mac with IOKit via the default HID MacOS driver. I am using IOHIDManager to detect it and send reports to it. I would like to extend this capability to iPad but the full IOKit framework is not supported on iOS/iPadOS. I saw that USBDriverKit is now supported on iPads with an M1 chip or newer. But, both MacOS and Windows can operate the device with their generic HID driver. As such, having to create a whole custom driver to interact with an HID device on iOS is really overkill. Would registering it in the MFi Program and operating it with the External Accessory framework be the correct route to take here? Or is there another framework for controlling HID devices on iPad over USB that I am not aware of?
