I have a mostly stable system (barring a few issues with sleep)...as long as my backup external HDD and Logitech c920 webcam aren't plugged into USB. The issue seems to be worst with the 3.0 ports, but I have gotten a freeze from the webcam in a 2.0 port. Sometimes it will freeze immediately upon being plugged in. Sometimes if booting with accessories plugged in, the machine runs strangely, not connecting bluetooth for a minute or two, and then after a few mins it will hit a hard freeze. Since this is now happening with two different USB devices, I can say that there isn't anything wrong with the external HDD. There is, however, a chance that the webcam itself is broken. I just bought it today and this is the only picture I can get from it when in Quicktime, Photo Booth, and Skype:
mostly static with one strip of pixels that seem to change dependent on motion in front of the camera. Now this could be a defective device, or it could be something wonky going on with the USB hub, and not communicating the right picture. Who knows.
My first issue is to solve the USB freezing, though, and then I can assess the webcam. I have read other threads that suggest removing the GenericUSB kext. I do not have this in /S/L/E, though, and did not choose any USB-related kexts in MultiBeast settings when I configured things. I repaired permissions with Kext Utility and rebooted. Same problems. Anybody have any idea what I should try next?
