USB connection disconnects, still detected

[EddyP]

Hi,
I am having trouble with my Proxmox not connecting to my Skyconnect-dongle.
I installed Proxmox on an old laptop I had lying around, and have also tried on another one with the same result.
For some reason, the dongle connects and then disconnects, and there seems to be no ttyUSB* in /dev/ either.

Output when running dmesg after reconnecting the dongle:

While I can't get the dongle set-up in for example a zigbee2mqtt-container,
I have an VM running HAOS where I can successfully import the dongle as an USB Device(usb0) and use it with ZHA.
