+Overview
+
+This README will address issues regarding how to configure the kernel
+to access a USB HP Scanner.  The scanner should support the Scanner
+Control Language (SCL) so that applications such as SANE can access it
+properly.  Refer to the document README.hp_scanner_sane for guidance
+on how to configure SANE to use the USB HP Scanner.
+
+
+Requirements
+
+A host with a USB port.  Ideally, either a UHCI (Intel) or OHCI
+(Compaq and others) hardware port should work.  However, I've only
+been able to really use an OHCI controller.  I did have access to a
+system with a UHCI controller but some very limited testing did not
+produce satisfactory results.
+
+A Linux kernel with USB support (preferably 2.3.15+).
+
+A Linux kernel with USB HP Scanner support.
+
+
+Configuration
+
+Add both USB controller support and USB HP Scanner support using `make
+menuconfig`.  If you decide to use the ohci-hcd driver, don't forget
+to add HUB support.  Compile and install the modules.  Testing was
+performed only as modules, YMMV.
+
+Add a device for the USB scanner: `mknod /dev/usbscanner c 16 1`
+
+Set appropriate permissions for /dev/usbscanner.  Both read and write
+permissions are needed for proper operation.
+
+Load the appropriate modules:
+
+  OHCI:
+
+    modprobe usb-ohci
+    modprobe hp_scanner
+
+  OHCI-HCD:
+    modprobe usb-ohci-hcd
+    modprobe hub
+    modprobe hp_scanner
+
+That's it.  SANE should now be able to access the device.  
+
+There is a small test program (hp_scan.c) that can be used to test the
+scanner device.  It's purpose is to test the driver(s) without having
+to retrieve/configure SANE.  Hp_scan.c will scan the entire bed and
+put the output into a file called out.dat in the current directory.
+The data in the file is raw data.
