Subject: [PATCH] rosemary: Set default the Bluetooth class of device The class
 of device is a string with a list of uint8t values: 90,2,12

The meaning is as follows:

Service Field: 0x5A -> 90
    Bit 17: Networking
    Bit 19: Capturing
    Bit 20: Object Transfer
    Bit 22: Telephony
MAJOR_CLASS: 0x02 -> 2 (Phone)
MINOR_CLASS: 0x0C -> 12 (Smart Phone)
