On the client side, you need to build usbredir and rebuild spice-gtk
with usbredir enabled.

On the server side you need to build usbredir and rebuild Qemu with
usbredir enabled.
You also need to add to your VM configuration some USB devices and
attach them to SPICE.
See SPICE User Manual [1] "USB redirection" for details.
