unplugging logitech quickcam pro crashes vbox guest => Fixed in SVN/3.0.8

[Tor houghton]

After reading that USB high speed devices were somewhat supported, I thought it would be an idea to try my ​Logitech webcam again.

Bus 002 Device 021: ID 046d:0991 Logitech, Inc. QuickCam Pro for Notebooks

No picture appeared, so I decided to unplug the camera, which resulted in the whole session being aborted.

The host's log did not show anything:

The second time I tried this (and reproduced the bug), I did manage to get a picture from the webcam within the guest (albeit frozen).

Any chance to send me a ​core dump if the VBox session crashes this way the next time? If so, please contact me via private E-mail at frank _dot_ mehnert _at_ sun _dot_ com. And please, just attach the whole VBox.log file, don't copy'n'paste any parts of it.

Bug is hopefully fixed in the next release.
