That's the use case for USB redirection. Spice has spice-usbredir
channel which uses the usbredir library to do USB over tcp from
your client to remote QEMU.

As far as I know, usbredir works on Mac but I don't have one at
hand to test. If you are using spice-gtk, the client needs to be
built with that enabled.

If you are allowed to change QEMU command line arguments, you can
use setup usb device over a network port, that uses usbredir
protocol too. Then, you can use usbredirect binary (from usbredir
library) to redirect the local device.

All suggestions considering that usbredir works in your platform.
