idallen

I have a similar problem with an ASMedia device. Ubuntu 20.04.3 LTS Linux idallen-oak 5.13.0-27-generic #29~20.04.1-Ubuntu SMP Fri Jan 14 00:32:30 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux I have a StarTech SDOCK4U33 4-slot USB 3 hard drive dock using ASMedia Technology: Bus 004 Device 007: ID 174c:55aa ASMedia Technology Inc.

If I unplug the hard drive dock USB cable, the machine boots fine. If I then plug in the dock USB cable after the machine is up and running, the above error happens (and I again lose many other USB devices). Surely plugging in a USB device should not cause the whole controller to fail and lose all the other working USB devices? If I power off all of the drives in the hard drive dock and then power them on, that seems to reset the dock and then everything works fine again when I reboot. The dock is correctly detected at boot and everything works. If I then reboot with the dock running, the problem returns until I power cycle the dock and reboot again. There is something about this dock that xhci_hcd doesn't like when the dock is left powered on across a reboot. More details (syslog, etc.) upon request.
