USB issue after plugging it


Mar 1, 2021

I have the latest version of Proxmox installed on a mini PC (Core I9 64GRAM 1T nvme).
I have a WIN11 VM which works well and I have attached a touch screen (HDMI with USB)

The GPU Passthrough works well, I start the VM and everything works. After 1min about, the screen still shows up the desktop, the VM runs but the touch screen doesn't reply anymore. I tried to remove the USB and replug it, it works again for 1 min:

If you have any ideas :) Many Thanks
i don't see a usb passthrough config in your vm config, is that deliberate ?

i'd check the energy settings for the usb port for example
Thank you for your reply. You are right, but on the GUI I see my usb:

Not sure what USB specs your touch screen has, but:

- try plugging in the touch screen directly into the mini pc, without any USB hubs etc.
- try switchting the touch screen between USB 2 and USB 3 ports (high speed, full speed)
- double click (edit) the USB properties in the vm (your screenshot) and activate/disable USB3,
try Use USB Vendor / Use USB port

thats not the same vm, you posted the config of vm '100' and the screenshot is of vm '101'

also, please check the usb energy saving settings (bios/host/guest) maybe they get automatically suspended, etc.
Oh my god, my mistake:

Already tried to remove the USB and replug it. It works for 1 min too.

Already tried to change the USB port. It works for 1 min too.
I will check for usb energy saving settings (bios/host/guest) but for other VM it works well, no issue.
I will test also to deactivate USB3. For USB Vendor / Device ID, already tested, not worked
