218e99
The usb-host code has been rewritten for qemu 1.5 to use libusb,
218e99
the old code has been left in as temporary fallback.  Now we are
218e99
two releases further out, targeting the 1.7 release.  No major
218e99
issues with the new code poped up until now.  Time to remove it
218e99
from tre tree.  Should we ever need it again for some reason --
218e99
git has a copy for us in the history.
