I have a device which is a programmable bridge by Cirrus Semiconductor.
It converts parallel TTL to USB2.  I've built udev rules to upload its
firmware when detected (by VID/PID), and to set the permissions and a
systemd alias of its new identity after the firmware is loaded.
Are you using qemu-traditional or qemu-upstream for this HVM guest?
Note that qemu-traditional only supports USB 1.1 emulated passthru,
while qemu-upstream also supports USB2 and USB3.
Using qemu-xen-traditional, as I must have VGA passthrough.  This USB bridge is a USB2 device and must work at those speeds.  Is this going to be possible?
More info in my next email.
