USB hub failing under Monterey

This is ******* ridiculous. FIX THIS!! It's completely destroyed my workflow and productivity. A ******* USB hub bug. **** YOU, ******* fix this Apple what the ****

One temp workaround I have used with previous Macs and seems to work with my issue, which was after upgrading to Monterey my Anker usb-c port extender worked fine except for supplying power to the Mac (I had the usb-c power cord plugged into the usb-c charging port of the Anker).

Go to Terminal and paste in: sudo killall -STOP -c usbd

It will ask for a password to confirm.

I used this just now and then unplugged / replugged in the Anker with the power cord attached and the battery display message changed from Not Charging to the displaying amount of time to full charge. Now my battery is at least constant as I work (I think the amount of power the Anker allows through is limited?)

Same here, since updating to Monterey (now 12.4) sleep stops power delivery from the USB Hub, so wake up fails to wake the external HDMI monitor attached to the hub. This is specific to certain hubs it seems, the Apple stock "USB-C Digital AV Multiport Adapter" does not experience the same issue.

It would be fine if there was an official supported Apple product that provided Ethernet, HDMI, etc, but since there is not Apple should try not to break third party ones.

Hey everyone, before you give up try flipping the connector over and trying again. Apparently, if you connect USB-2.0 devices, this is a limitation of the protocol.

In my case I'm using a USB-C extension cable from my hub to my laptop (female to male). Flipping the connector on the laptop side did not work, but once I flipped the connection at the hub side (female in my case) my USB-2.0 devices started working!

FYI before finding a fix, my devices were powered but not connecting to the MacBook, like a lot of users here.

Has anyone tried upgrading to the Ventura beta and seeing if this fixes the issue?

Ive found a fix for my problems, it seems MacOS became a bit more touchy on unstable power, perhaps it doesn't like my docks power supply, im not sure. So i just power the mac with a seperate power supply while docked, no more issues.

Hope this helps some of you aswell.

My Mac and dock have been powered separately from the beginning. Very curious that some fixes work for some people. And that Apple has not acknowledged this bug.

go terminal and run "sudo killall -STOP -c usbd". After that, reconnect HUB.

Looks like problem is in some kind of usb daemons get stuck after that commend they will restart immediately

It helps me with Baseus hub

respect goes to MM73

12.6 the same problem, the usb ports stopped working, you can charge it but the flash drive does not open

What a disaster.

I learned my lesson. I'm not updating until my IT Admin threatens to fire me!

I have a TOTU hub for macbook pro. Worked perfectly before I did update to 12.6 and now nothing. Tried all workarounds mentioned in this thread with no luck. Anyone know of anything else to try?

I even downloaded the beta of Ventura- STILL same issue.. what the heck Apple???

How can this issue be so old, then transfer to the next OS?!? I am using a Micro Center purchased quality USBC hub with two USBA spots on it. Everything was fine, then USBA webcams stopped working. Seemed intermittent, I was able to get the GoPro10 working from time to time, then not but the cheap Onn worked beyond the Logi, then they all stopped. My USBA Mackie mixer and Pioneer DDJ-SR controller still work, and my external hard drives are fine. I tried the sudo killall command pages above, nothing. I'm not doing any safe mode nonsense just to have it stop mid-stream again. $2200 laptop, can't use simple devices. I tried my quality USB3 powered hub out of the USBC hub, nothing changed; power not the issue. Everything works on the ol 2015 MBP workhorse. Neigh...

j5create JCA374 hub doesn't work with Monterey 12.6. Tech support wasn't helpful. No drivers available.
