Open KVM monitor for your KVM machine in Proxmox GUI or in the command line with the following command:
# qm monitor 168 Entering Qemu Monitor for VM 168 - type 'help' for help qm>
Show the usb devices info from your host machine:
qm> info usbhost
Bus 4, Addr 2, Port 1, Speed 12 Mb/s
Class 00: USB device 046b:ff10, Virtual Keyboard and Mouse
Bus 6, Addr 2, Port 2, Speed 1.5 Mb/s

According to device “USB device 0930:6533” in the example, add the device to guest machine:
qm> device_add usb-host,id=myusb,vendorid=0x0930,productid=0x6533
Verify that the new usb device is added in your guest:
qm> info usb Device 0.1, Port 1, Speed 12 Mb/s, Product QEMU USB Tablet Device 0.3, Port 2, Speed 12 Mb/s, Product QEMU USB Hub Device 0.4, Port 2.1, Speed 480 Mb/s, Product DataTraveler 2.0
After using it, remove usb device from your guest:
qm> device_del myusb
If you run the command again, you will see the usb device is gone from your guest:
qm> info usb Device 0.1, Port 1, Speed 12 Mb/s, Product QEMU USB Tablet Device 0.3, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
This has been tested in Proxmox 3.0/957f0862
Thanks for this info, the first working one I found voor v3.
I ran into one little issue: two of my USB devices have the exact same vendor and product ID. They both use SI labs drivers/systems.
Any idea how to get around this?
Bus 2, Addr 11, Port 1.5.6, Speed 12 Mb/s
Class 00: USB device 10c4:ea60, CP2102 USB to UART Bridge Controller
Bus 2, Addr 12, Port 1.5.4, Speed 12 Mb/s
Class 00: USB device 10c4:ea60, CP2102 USB to UART Bridge Controller
Late, late, late :-), but you can try to specify other parameters like
qm> device_add usb-host,id=myusb,vendorid=0x0930,productid=0x6533,hostaddr=11
Thanks for the article. It works!
