QNAP issue with usb Zigbee stick

Hi, I have installed the HASSIO ova as a VM in the Virtualisation Station of my QNAP TS473 and had for some time a CC2531 ZigBee USB-Stick which was working properly and flawlessly.
For some reason about a month ago it started being disconnected from the VM and when trying to connecting it again, after a few seconds it was getting disconnected! i though the USB had a problem, so I got a Conbee II. Again the same problem! Once added to the VM (as USB) it gets disconnected a few seconds later.
Any idea why and how to fix it?

My system TS-473 with fw v5 has:
Home Assistant Core 2022.5.4
Home Assistant Supervisor 2022.05.2
Home Assistant OS 8.0
Kernel version 5.15.38
Agent version 1.2.1

thank you.

Hi

I know that this is an old topic but I don’t suppose you found a solution?

Having the same issue with ZigBee sticks crashing all other usb ports and disconnecting so sounds very similar on my QNAP nas!

Many thanks
