I have several USB Devices plugged into my proxmox machine via USB hub. One of them occasionally goes into an "Unknown" state like this:

and only recovers when I unplug and plug it back in. The only difference between this USB device versus others is that I have covered "Power" pin of the usb connector because otherwise it keeps constantly powering the screen my 3D printer, even if the printer is off. Could the covering of power pin cause this? Or is the issue more likely somewhere else?
 
hi,

dmesg output might shed some light to the issue. also check the lsusb output before/after device goes into this state
