[Spice-devel] [spice-gtk v1 1/4] usb: use native libusb procedure for getting error name

[Victor Toso]

From: Yuri Benditovich <yuri.benditovich at daynix.com>

libusb has libusb_error_name procedure that returns name
for any error that libusb may return, so we do not need
to analyze error values by ourselves.
