check with "hciconfig hci0 revision" and "bccmd buildname" (both as
root) if they have a special Dell firmware running on it. If not then
there can be still a Dell custom application running in the VM of the
Bluetooth chip.

Best bet is to ask Mario from Dell if he can help us out here and maybe
make HID/HCI switching persistent across reboots. If not then we might
have to write a bluetoothd plugin that does the job for us.
