Heya,
I’m trying hard to get my conbee II zigbee stick working on my proxmox host :/

Right now I can’t find the issue with it. The stick itself can’t be the problem because switching the stick to my old server is working just as expected.

Code:
lsusb
just shows me the Dresden electronic conbee stick and if I do a
Code:
ls /dev/tty
I can find my device under ttyACM0 but after a couple minutes or maybe just 30-60 seconds the device disappears und /dev/tty… but is still visible under lsusb.

What information is needed to help me debugging this?

Ty all in advance!

Kind of the same issue here. But it's not limited to the Conbee2 device. Another RS458 device has trouble as well. Trouble started after upgrading from 6.3 to 7 two days ago. Before that the USB connection was rock stable.

For me, the device disappears completely after some minutes. `dmesg` shows the following after I unplugged the device from the host and plugged it back.

Any hint of how to fix this is really appreciated. But reading other issues related to USB and what not, downgroadnig seems to appear quite often. :eek:

Hey there, its me again.

I'm still having issue with this. I will try to turn off IOMMU in the bios now.

Here an actual screen that shows the first message with an error and after it, it starts struggling with the USB device:
