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.
