Hi Marcel,

No, i didn't. The factory settings of my BT-600 are:
phobos:/home/harbaum # hciconfig hci0 revision
hci0:   Type: USB
        BD Address: 00:02:72:B1:59:03 ACL MTU: 192:8  SCO MTU: 64:8
        HCI 16.4
        Chip version: BlueCore02
        Max key size: 56 bit
        SCO mapping:  HCI

But so says the DBT-120 dongle i did not have success with:
hci0:   Type: USB
        BD Address: 00:0D:88:C0:3C:E4 ACL MTU: 192:8  SCO MTU: 64:8
        HCI 15.3
        Chip version: BlueCore02
        Max key size: 56 bit
        SCO mapping:  HCI

I tried this command at work with the microsoft dongle, but the i only got 
16.1 as the hci version and then the program hanged. The kernel log showed 
some hci timeouts.
