Hmm, this sounds like you are using spice usb-redir too and the 2 are fighting
each other. Which spice-client are you using? And are you plugging in the
device after starting up the vm ?

Good.

Why not? Looking at your qemu cmdline you are using spice. Hmm, I guesss you
may want to keep the device redirected when no client is connected?

Anyway, if you could remove the host-redirection temporarily and try with
spice usb-redir and collect logs that would be great. If you don't have
time for that, that is ok too, then I'll consider this issue resolved.
