I would like to use virtual-fido on a PinePhone running Linux, providing a virtual FIDO device over USB to my laptop and desktop both also running Linux. Using USB over IP makes that more complicated, since I have to share network between the two devices and then run usbip commands, so I think it would be great if virtual-fido could support the Linux USB gadget subsystem in addition to USB/IP. If you don't have a Linux device capable of gadget mode, the dummy_hcd Linux kernel module can be used to add virtual USB gadgets to your laptop/desktop. I don't know if there is a golang library for Linux USB gadgets, but the @linux-usb-gadgets GitHub org has a C library and command-line tool for this and there is a less maintained D-Bus daemon too, which could be useful on a phone.
