Here's the corresponding output on my system:
Bus 001 Device 024: ID 1131:1001 Integrated System Solution Corp.
KY-BT100 Bluetooth Adapter
hci0: Type: USB
BD Address: 11:11:11:11:11:11 ACL MTU: 678:8 SCO MTU: 64:10
Note my BD address is also "11:11:11:11:11:11". These cheap dongles
appear to all have the same BD address. That will cause problems if
two of them are in range of each other; it's similar to having to
Ethernet cards on the same network with the same MAC address. This is
a violation of the Bluetooth spec - those IDs are supposed to be
unique. I suppose you get what you pay for.
If the BD address is the same for both machines, I don't think it's
going to be possible to get them to talk to each other. They should be
able to talk to other devices with other, unique BD addresses, but
they will get seriously confused trying to communicate with each
other.
Some Ethernet cards allow you to change their MAC address; anyone
know of a way to change a dongle's BD address?

Tested; working with more than one device (both mobiles - one a Sony
Ericsonn, and other a Motorola A920.
I also cannot get to use rfcomm0 or bnep0 interfaces up.
