Every time I use my Nikon Coolscan IV LS-40 USB scanner the usb driver crashes after scanning a small number of frames with the message:
Mar 10 03:13:48 kletskop kernel: usb_control/bulk_msg: timeout Mar 10 03:13:48 kletskop kernel: scanner.c: write_scanner: NAK received. This is with linux-2.4.20 and in fact it has been a problem with all stable linux kernels that I have tried. Kernels <= 2.4.18 would crash within a few seconds, while kernels >= 2.4.19 do a decent job until they crash after some 10-15 minutes scan time. I am using vuescan which is also available for windows; when booting my computer in Windows the exact same hardware runs vuescan without problems, so I am assuming it is a problem with the linux usb driver. To be sure I have bought a new usb pci card (uhci instead of the motherboard ohci) but this did not help. So the problem is with both the usb-uhci and usb-ohci module (or something that they share). I saw a message on this mailing list by Martin Thornquist dated 2002-05-30 where he described the same problem. Could anybody out there suggest a remedy? If you need more details, please let me know.
