USB devices dying!
« on: September 12, 2008, 05:30:05 am »

hi everyone, searched the forums, searched the interwebs, can't find a solution! I hope some kind soul can help me!

it seems every time i leave my system idle for a while, the USB devices stop functioning, I have a USB mouse, and a USB wireless adapter, and whenever i come back to my PC and the screensaver is on, the mouse doesn't work, and the light on my wireless adapter has turned off. I'm not sure whether this is to do with xscreensaver or what, dmesg doesn't give me any useful information, turning off ACPI hasn't stopped it, i don't know what to do! I'm going to disable the screensaver to make sure it's not something else, although it does appear to be the culprit, i haven't encountered this problem if i've come back before the screensaver activates.

please help!

Did you check /var/log/messages?

My guess is would be hibernation is the problem
or something that cycles the power mode on the
the USB devices. One place to look would be the
Bios to see if any power modes are available.

well my computer's been sat idle for the last 3 or so hours with xscreensaver disabled, and everything is working ok! /var/log/messages refers to 2 USB devices being removed, but i don't know what to make of the lines around it, here it is:

Code: [Select]

Sep 11 12:44:39 vector gconfd (ricardo-19067): Exiting
Sep 11 12:44:58 vector shutdown[19173]: shutting down for system reboot

I'm guessing that's where things went wrong, but i doubt gconf had much to do with it, although i don't know much about it!

I'd quite like to get to the bottom of this, i'll check my bios later

I'm using 5.9, not sure which edition exactly, the one with xfce. should gconfd even be running? i don't use gnome!
