Comment 1 for bug 776206

On the other hand, the Debian patch seems to be correct but libusb-0.1 is not maintained by upstream. Instead, the upstream maintains libusb-1.0 and libusb-compat-0.1 which many other distros ship.

So this may not a bug for Debian/Ubuntu but it conflicts with other distros shipping with original libusb-0.1 usb.h or libusb-compat-0.1.

Ludovic Rousseau has sent in patches to libusb mailing list. Hopefully the libusb admins can accept this patch. In that case, this bug report can be closed.
