View Full Version : [ubuntu] HP 4200c Scanner lamp won't sleep

Ubunto 8.10
HP 4200c Flatbed Scanner (usb)
xsane 0.995

Principal scanner functions are OK.
However, scanner will never sleep, lamp stays on all the time.
I found a post with a similar problem on an HP6300 scanner. Poster ultimately noted that theirs worked OK following update to Ubuntu Ver 9.04, but no such luck for me.
I've found various forum posts noting that ANY usb activity can cause similar problems, but my problem persists even though the scanner is the only usb device connected. This model Scanner does not have a true on-off switch, so turning it off isn't an eaxy solution without unplugging cables.
