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.
