i'll bring out that gun if i have to, so far so good with the masking the scanner approach. the keyboard hasn't dropped all afternoon *knocks on wood head*... my previous searches for help on-line didn't get me far because i was using powerd and power instead of autosuspend. when you're not sure if the problem is the kernel or the device it's hard to know what to search for first. :) songbird
