[Spice-devel] USB-redirection

[Trebor Forban]

Hello,

can anyone give me a clue where to start looking?

Could this be caused by libs that are in the "normal" system, but not
in the minimal system?

Could it be caused by missing services/daemons?

I really don't know how to go about debugging this.

Regards,
TF
