Using USB in a VM on the FW 13/16

Framework Laptop 16 Linux
1

All,

My question is about sharing USB to a virtual machine. My understanding is that all expansion slots are USB ports as far as the motherboard is concerned. Meaning, if I have an HDMI expansion slot it gets converted to USB and then goes to the motherboard.

If I have Ubuntu 24.04 as the host is and Windows 11 as the guest using VirtualBox, if I need access to a USB port (one of my expansion cards) in the Windows VM will all the FW expansion cards be mapped to the VM? Or, can I control which get mapped? Since all expansion cards are USB in the end, I’m worried that once I share USB with the VM then all of them will disappear from the host os.

Help?

You can filter by specific device:

Example with virt-manager (linux):

With Linux and KVM, you can pass through the device based on its id/serial number.
Rather than assigning a specific physical port to it.
There might be a similar feature in vbox.

Great to hear. Thank you!
