USB passthrough problem

[Xoxe]

Hello, i´ve just installed Proxmox with 2 VM (Home Assistant and Octoprint), i have attached to it a webcam and a 3D printer. Proxmox can see them perfectly but none of the VM can, i tried all the options under "Add USB device" but no one working.

Do you know if i can fix it?

Are you trying to pass it to a Windows or a Linux VM? Did you shutdown the VM completely after configuring it and then restarting it?

Both are Linux VM and yes, i restarted all, many times.

Webcams appear to be problematic with USB passthrough. It can often be resolved with PCIe passthrough of a whole USB controller, but that also comes with lots of caveats and other limitations.
