Hi
I've been using Davis Envoy + Weewx combo since 2011. About year ago I moved Weewx from bare metal to Proxmox VM. Since that I have got ftdi errors every 1-4 weeks that can be solved only by pulling usb-plug out and putting it back again (for example system reboot does not restore communication - ftdi chip needs to be actually depowered):

Any ideas how to solve this problem? Is there command that would reset ftdi chip communication without physical interaction? I have old RS232 interface somewhere, mayby some other USB UART would work better? Slowing down communication (currently as default 19200)? I had zero problems with this adapter on bare metal, but with new server hardware (Supermicro motherboard) I have used only VM.

Proxmox gives quite limited usb passthrough options, only usb3 forcing, but problem remains regardless this.
Debian VM (bookworm/sid) is currently running kernel version 5.16.7 and Proxmox 5.13.19.
Any ideas how to solve this problem? Is there command that would reset ftdi chip communication without physical interaction? I have old RS232 interface somewhere, mayby some other USB UART would work better? Slowing down communication (currently as default 19200)? I had zero problems with this adapter on bare metal, but with new server hardware (Supermicro motherboard) I have used only VM.

are that you are running a USB device drive in a VM, either PCI
passthrough to the controller, or to an emulated controller which is
then talking to hardware. You should understand what's really
happening and it is likely pretty complicated.
I don't know if weewx has easy support for this, but if you can run a
process in the dom0 (host kernel on the hardware) and then connect weewx
to that over TCP from inside the VM, you will have removed all the USB
driver issues from the VM.
