Hi. Has anyone succeeded in getting a RS485 to USB dongle working in a VM with Home Assistant. I managed to configure a passthrough with Vendor/Device ID, ttyUSB0 does show up in /dev in the HA VM, but it does not communcate at all with a Modbus server. The exact same config but without proxmox on a vanilla Linux box works fine. Thanks.

Have you also tested USB version 2/3?
Do you see anything in the logs that could help?
What OS are you running in your VM?
