However you can execute "hcitool cmd 3f 3b 00" by hand > and after that the mouse and keyboard devices provided by this dongle > should disconnect and you can fully use the Bluetooth part. so everyone with the IOgear GBU311 or the Microsoft Wireless Transceiver for Bluetooth 2.0 should test the attached kernel patch and report back. The patch will apply cleanly against 2.6.10-mh3 and 2.6.11-rc3.
