Hi, the debug log shows lots of times a "read failed. End of file reached". Please try the current CVS-version of the hp-backend. I just added a retry for that case.
You can also try to get around the USB-scanner module and work directly with libusb. This sometimes works better. Make sure that the module scanner is not loaded. Rename the object /lib/modules/2.4*/kernel/drivers/usb/scanner.o to scanner.o_save Then connect the scanner with your machine. It should be recognized. Try to scan.
