[PATCH] USB: Fix usbfs regression

I have just tested kernel version 2.6.11-rc5 and noticed it is not
possible to do an USB transfer by submitting an URB to an output
endpoint.  This breaks newest versions of libusb and thus SANE, gphoto2,
and a lot of software.

The bug was introduced in version 2.6.11-rc1 and is due to a wrong
comparison.
