I recently bought a Hama bluetooth 3.0+HS dongle. I'm using it with my Ubuntu 10.04. Ubuntu recognizes the dongle and I am able to set up BT devices. But how can I check whether it is actually using version 3.0 rather than 2.1?

Run the hciconfig -a command, it'll list all Bluetooth devices and the supported versions

hci0:   Type: BR/EDR  Bus: USB
        BD Address: 00:1C:7B:A5:91:F2  ACL MTU: 310:10  SCO MTU: 64:8

        HCI Version: 2.1 (0x4)  Revision: 0x12e7
        LMP Version: 2.1 (0x4)  Subversion: 0x12e7
        Manufacturer: Cambridge Silicon Radio (10)

As you can see, my device only supports 2.1 (HCI Version).

Alright. Can I somehow also check for the HS channel capabilities? –  koloman Mar 21 '12 at 8:53
    
I don't know, try searching in the manual pages or the ubuntu help pages. –  Lekensteyn Mar 21 '12 at 10:58
