Bluetooth detection and use is very unstable with gnome-bluetooth and/or blueman.

Every attempt to scan for devices, via "hcitool scan", blueman or gnome-bluetooth applet results in a kernel: hci_cmd_task: hci0 command tx timeout in /var/log/messages.
This bluetooth adaptor is a tiny one with no brand.
