 USB-scanners:
 -------------
 USB-Scanners are supported in principle since OpenBSD 2.9. The USB scanner
-driver "uscanner" and access over libusb is supported. To get your scanner
-detected by the uscanner driver, it may be necessary to add it's vendor and
-device ids to the kernel and recompile (sys/devs/usb/uscanner.c). With OpenBSD
-3.0 there is also a bug concerning uscanner that prevents accessing the
-/dev/uscanner devices.  Get a newer kernel in this case. If your MAKEDEV won't
-make /dev/uscanner0 do it manually: "mknod /dev/uscanner0 c 77 0" for the
-first scanner. Edit your backend's configuration file appropriately.
-If you want to use libusb, your scanner should *not* be claimed by the uscanner
-driver.

+DIAGNOSTIC. If it is, you will get errors like "ugenioctl: USB_SET_TIMEOUT,
+no pipe". Make sure, that /dev/ugen* and /dev/usb* devices are available. Use
+/dev/MAKEDEV to create them, if necessary.
