I need help with reproducing a crashing/freezing problem on my powerbook. The problem is related to USB. I have a 1.25Ghz 15" powerbook with the following USB problems: When I have a USB mouse plugged it it will periodically freeze (stop working). I can unplug and replug the mouse and it starts working again. Very rarely, it will crash. I've tried two mice, they both do it. When I have a USB keyboard plugged in it will periodically freeze (like the mouse, unplugging and plugging will start it working again). Semi-frequently, it will crash. I've tried 4 keyboards, they all do it. I've taken my notebook in for servicing, it's under warrenty, but they were unable to reproduce this. I can understand this, it happens enough to make it not useful for work (crashing is a serious issue while working), but not enough that I can reproduce it at will, and I don't expect them to test my notebook all day. Does anyone have any tips for consistently reproducing this? Beyond the obvious of plug a mouse/keyboard in and generate input. Has anyone experienced a similar issue?
