USB 3.0 Hub Broken on Mac OS Monterey 12.0.1

Since upgrading to Mac OS Monterey, solely the USB 3.0 port on my Hub has stopped working. Power is allowed to pass through to connected devices, however the transfer of data has stopped working.

Everything was working on Mac OS Big Sur, and it is only since updating to Monterey it has stopped working. I have found several reports on the developer forums for Mac OS stating this was an issue since around Beta 3 for some users, and there are reports on Reddit of other people having this issue.

Apple Support were useless and told me to bring my Mac in for repair (despite it only being 4 days old and the issue happening directly after an update) I took the Hub back to the place of purchase and they tested it on a Mac with Big Sur installed and it worked. When plugging it into another Mac that had been updated to Monterey the 3.0 Port stopped working.

It's an Advent Hub, not some dodgy knockoff one of Amazon. It worked absolutely fine prior to the Monterey upgrade.

Now when plugging in my iPhone via USB 3.0 or my Mouse, all that happens is the LED's on my mouse light up (but not the laser) or my iPhone charges, but won't connect to my Mac.

Oddly, both the HDMI and USB-C port on the hub continue to work as expected.

MacBook Pro 13″, macOS 11.6

Thanks for your response.

Unfortunately I don't have an Intel Mac to test this on, both machines tested at the place of purchase were M1 based Macs. My Mac, is also M1 based.

M1 with Big Sur = Working USB Hub

M1 with Monterey = Broken USB Hub with only HDMI and USB-C working on the hub, but no USB 3.0

It would be interesting to test with an Intel Mac on both Monterey and Big Sur, to see if the issues are consistent across both chipsets and OS's. The fact of the matter is though, my M1 based machine worked fine with this hub on Big Sur, and Monterey has changed that.

The worst USB drivers in the world are in Mac OS since 1998.

USB 3.0 external drives also no longer work.

Is this USB bug going to be fixed? My MacMini (2014) is now worthless without the ability to access data on the USB 3.0 attached drive.

ARG!

I’ve done all of that, and they try to say the problem is with the hub that is not compatible. Trying to put the problem on the others

If the hubs works before update, the problem is definitely on the OS, simple like that

I ultimately ended up buying a new UGreen hub of Amazon, and it works.

Not a fix not a solution as there was nothing wrong with the original hub, apart from Monterey broke it.

when hundreds of users report that the usb hub worked perfectly under Big Sur, there is reason to believe that the driver is at fault !

Try a USB 3.0 gen1 or USB-C 3.1 gen1 cable that is USB-IF certified.

Those are the only cables I can get to work. Even the 3.1 Gen2 cable supplied with my dell monitor doesn't work!!
