We have just the same situation on one WS here - HP scanner without SANE 
support. We use usbredir:

Few (4) <redirdev bus='usb' type='spicevmc'/> channels in the libvirt 
machine definition and:

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Icon=/usr/share/icons/HighContrast/scalable/devices/computer.svg
Exec=/usr/bin/remote-viewer -f 
--spice-usbredir-auto-redirect-filter='-1,0x03f0,0x3b05,-1,1|-1,0x04a9,0x1900,-1,1' 
--spice-usbredir-redirect-on-connect='-1,0x03f0,0x3b05,-1,1|-1,0x04a9,0x1900,-1,1' 
spice://127.0.0.1:5906
Name=xp6

03f0:3b05 is our HP Scanjet N8400
04a9:1900 is some other device we want to go to XP.

Kind regards,
