USB to bluetooth adapters

hello,
i want get a bluetooth module connected with beagleboard xM rev C.
the ref manual gives three products which suits to it but at the same
time says it has not been tested.
the suggestions are like these
TBW-105UB,
ABT-200,
F8T012-1
i am intending to boot BB through angstrom linux.
  so i need the help of suggesting the right BT adapter which works
well with BB and finally the goal of this bluetooth device in our
application is to recieve data from CC2540 ,a TI product.

hope someone helps...

with regards..
