I run into this maybe once a month.
(installation details are at the bottom)
my kyocera laser printer (usb) cuts out and won't respond.
Restarting cups takes a very long time and the CUPS web pages don't show any problems with the cups system.
The only messages in my syslog are: Dec 7 05:19:55 localhost last message repeated 2 times Dec 7 05:20:00 localhost kernel: usb 1-1: control timeout on ep0in Dec 7 05:20:26 localhost last message repeated 5 times Dec 7 05:20:31 localhost kernel: usb 1-2: control timeout on ep0in Dec 7 05:20:56 localhost last message repeated 5 times Dec 7 05:21:01 localhost kernel: usb 1-1: control timeout on ep0in Dec 7 05:21:27 localhost last message repeated 5 times Dec 7 05:21:32 localhost kernel: usb 1-2: control timeout on ep0in Dec 7 05:21:57 localhost last message repeated 5 times Dec 7 05:22:03 localhost kernel: usb 1-1: control timeout on ep0in Dec 7 05:22:28 localhost last message repeated 5 times Dec 7 05:22:33 localhost kernel: usb 1-2: control timeout on ep0in Dec 7 05:22:59 localhost last message repeated 5 times Dec 7 05:23:04 localhost kernel: usb 1-1: control timeout on ep0in Dec 7 05:23:29 localhost last message repeated 5 times Dec 7 05:23:34 localhost kernel: usb 1-2: control timeout on ep0in Dec 7 05:24:00 localhost last message repeated 5 times
Power cycling the printer doesn't seem to help much...

So I'll try rebooting the entire cups print server. Not the solution I had hoped for. But rebooting the system works.
At this point I'll make the accusation that there is more of a problem with USB devices than with CUPS. But I never can tell with these things.
Any suggestions would be appreciated.
