Comment 18 for bug 133690

I have something similar on intrepid with my sitecom dongle (CN-521v2 001) connecting to a wireless apple keyboard. When I reboot the dongle doesnt connect with the keybouard properly unless I turn the power supply off after shutting down. Alternatively, removing the dongle from the usb slot also does the trick and the bluetooth connection with my keyboard is automatically reestablished after that.

Obviously the dongle is left in some state after shutting down that is different from powering up. and that doesnt recover properly. Remember the power stays on the usb port even when shutting down (unless you also turn the power supply off).

Thought it would be useful to share this .....
