See if this rings a bell. Instead of halting/booting my system every day, I prefer to suspend it to disk. Sometimes it happens, perhaps after a month without problems, that one day the scanner (epson 1650 via usb) is no longer there. I can not list it with lsusb. Gone. The only solution seems to be to reboot - down the flush goes my uptime! ;-)
This is with SuSE 9.3. Time ago, there was "rchotplug restart" that would force the usb bus to work again, but the script has disappeared. I tried reloading usb kernel modules, but it did not work; perhaps I did it wrong.
It seems the usb init script is now inside "/etc/init.d/kbd". I will try the method there next time it happens.
A colleague has been having similar problems with a different model of Epson scanner. He found that connecting the scanner directly to the PC rather through a hub fixed his problem.
I had a problem with some devices I had connected to a non-powered USB hub. Replaced the USB hub with a powered one and all of the problems went away. The one that had the most problems was a scanner. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998
