Hello,

I'm totally new to Proxmox VE and currently migrating my RB4 Docker Smarthome System to a Proxmox VM / Docker environment.
Meanwhile I was able to get most up and running, but experiencing an odd isse with my FTDI devices.

At the moment I'm using two Ubuntu VMs. VM1 serves as my IObroker instance. While VM2 is used for Docker running several containers including Openhab.
To control and monitor some of my devices two FTDI interfaces are connected via USB.
The HERMES USB DONGLE shall be connected to VM2 to control my in-house air ventilation system.
FT230X Basic UART is used to monitor my power metering device and shall be conntected to VM1.

Strangely only the HERMES DONGLE seems to work and for both(!!!) purposes. What I mean is, when I connect the HERMES to my VM1 I can control the air ventilation system. If I connect the HERMES DONGLE to VM2 I can monitor the power meter. To be clear, the HERMES DONGLE is physically connected with the central air ventilation unit.

In case of connecting the HERMES DONGLE to VM1 and FT203X to VM2 at the same time none is working.
I appreciate any help.
