USB disconnect built-in iSight camera


As of today the usb subsystem is cycling through USB addresses disconnecting my built-in iSight camera. I'm running Ubuntu 9.04 on a MacBook Pro 4,1. This is completely new behaviour, the last software update was over a week ago.

If it helps I can post the output of lsusb, however was quite large 2K lines.

Output of lscpi:
