Comment 27 for bug 291051

At this point, I think its related to the specific hardware you have. There's an Intrepid Stable Release Update out for this specific device as of like today.

You suggested other bluetooth "dongles" also did this. If you can, share the lsusb lines for them in case they're not currently known to be broken.
