 USB-Scanners are supported by FreeBSD. The USB scanner driver "uscanner" and
 access over libusb can be used.
 
-To get your scanner detected by the uscanner driver, it may be necessary to
-add its vendor and device ids to the kernel and recompile. Use MAKEDEV to
-generate the /dev/uscanner* files if they are not already there. Use
-sane-find-scanner to find your scanner and edit your backend's configuration
-file appropriately.
+For some backends (e.g. gt68xx) you MUST use libusb. The uscanner driver won't
+work because it doesn't support control messages or interrupt endpoints.
 
-If you want to use libusb, your scanner should *not* be claimed by the
-uscanner driver. Make sure, that /dev/ugen* and /dev/usb* devices are
-available. Use /dev/MAKEDEV to create them, if necessary.

 Parport-scanners:
 -----------------
-I don't have much information about these. The Mustek 600 II N scanner seems to work, others may or may not work. Please contact me or the SANE mailing
-list if you succeeded in using a parport scanner.
