I'm running linux 2.4.4 with the aic7xxx 6.1.13 driver as a module so I
can use a MicroTek ScanMaker X6EL scanner. It will scan some random
number of items, and then it seems to lose communication with the scanner.
This seems to require me to reboot linux to get things working again; just
rmmod and insmod of the driver aren't enough (insmod fails the first time,
but seems to run the second though). When the scanner dies, I get the
messages below. And Ideas?
If you need more information or have patches to test, I'd be glad to.
