first reason to play around with it: the remote version is wrong for
this bt-dongle. i think it should be 0x3 not 0x2.
second reason is, i want to find out, if its possible to "clone" a
bt-device. not only the address but also things like lmp-version or
features of a device.

when i am able to delete/clear a pskey, can also wonder if i can create
a new pskey entry.
