Re: Libusb-win32-0.1.12.1-1 makes system unusable after reboot.

Well, this happens with the old version too. But in the new version,
libusb0.sys is started differently from the old version, that possibly
makes the windows-provided usbd.sys discovery fail.

Err, no, usbd.sys is always installed in
c:\windows\system32\drivers\usbd.sys, and that's precisely because
libusb0.sys is not installed there too that the usual discovery fails.

Actually, I'm wondering: instead of trying to make libusb0.sys work
from /usr/lib/libusb/, is it fine (packaging-wise, I mean), in
libusb-install, to just copy it into c:\windows\system32\drivers\ and
then use the usual libusb-win32 filter setup?  That works fine and
actually makes the patch simpler...
