~ Using TP-Link TL-WN722N ~

The GUI way of adding a USB device to a Proxmox VM didn’t work for me when using a USB network adapter (the device id was not showing up when trying to add to the VM via the GUI), so here is a simple manual workaround.

- Steps:

1. Plug in your desired USB device into the physical machine you’re running Proxmox on.

2. Using the CLI on the Proxmox host machine (recommended to use ssh/webGUI CLI), list all connected USB devices with lsusb:

   

3. Note the ID of the desired device. In this case the TP-Link TL-WN722, with ID: 2357:010c

4. Ensure the desired Proxmox VM that you want to pass the USB device to is powered off, and take note of its number (104 in the below image):

   

5. Still on the Proxmox host machine, run the following command to pass the USB device through to one or more of your virtual machines:

   qm set [VM#] -usb0 host=[host-id]

   e.g. for VM #104 & host id 2357:010c, I would run:

   qm set 104 -usb0 host=2357:010c

   Source: Proxmox documentation

6. Boot up your Proxmox VM (in my case, VM #104) and run lsusb in using the CLI. You should now see the USB device that you just passed through (2357:010c for me) in there!

   

Hope this helps a few other fellow lost souls! ^^
