Re: [Bluez-devel] Continued SCO audio issues...

Ok, sorry for the confusion. :) We're using the Compulab EM-X270 SBC. It 
has a CSR BT chip on it that's connected to the machine via USB (a 
diagram of the basic interconnects in the system can be see in the 
document at http://www.compulab.co.il/x270em/download/x270-em-man.pdf). 
So, as far as I know it should be working in a similar fashion to a 
desktop PC.
