Hello,
I'm looking for debugging suggestions, and if any of this sounds familiar
to anyone.
I've got two USB devices, a HP 4100C scanner, and a Palm m500. I'm having
problems with both, although I'm not clear if related.
Accessing the scanner generates the usb_control/bulk_msg: timeout
messages, and I get generic I/O error reported in the front-end programs
(xsane never works, xscanimage sometimes works). I've tried both uhci
drivers.
I have sometimes seen these messages as well:
Jan 1 16:15:34 bumby kernel: scanner.c: write_scanner: NAK received.
Jan 1 16:10:11 bumby kernel: usbdevfs: USBDEVFS_CONTROL failed dev
3 rqt 128 rq 6 len 100 ret -110
I've discussed this problem on the SANE list and now feel it's either a
usb issue or hardware. The motherboard is not that old, and the scanner
and cable were working fine under Windows. (Although this machine does
not have Windows so can't test that combination of OS and motherboard.)
My second problem is with the Palm m500 and hotplug. I've posted this
question to hotplug list, but no response on that quiet list.
In short trying to use a /etc/hotplug/usb/visor script (or a usermapped
script) cause the Palm to hang at "identifying user" -- in other words the
hotsync starts and then hangs.
If I continue to try and hotsync the kernel will Oops and become unstable
and typically panics.
If I *don't* use a script run by the hotplug event and run the sync script
manually (i.e. rename visor to visor.tmp, let hotplug load the modules on
hotsync and then run ./visor.tmp manually) it all works fine. I think
that is odd.
I have a MSI K7T266-Pro2 motherboard with Via VT8233 USB conntroller. I'm
running 2.4.20 (SGI sources with xfs patches).
There are BIOS updates for my motherboard, but nothing that mentions USB
problems (and if I update my BIOS my ide-scsi drives fail).
I'm not a kernel hacker, but I'm willing to try any suggestions.
Thanks,
