Hi. I was asked to help diagnose a problem with a media center PC (a dell mini-desktop) through the phone. The PC was, according to the guy who installed the equipment, able to use a bluetooth home-teather type speakers. But suddenly the speakers would no longer pair at all. I was able to get him to boot the PC off a Linux live USB and had him post his lsusb and lspci. This is the lspci file

The wifi chipset is a rt3592bc8 which according to wikidevi contains built-in bluetooth. What I would like to know is if the bluetooth is showing up in the lsusb file (built-in bt chips usually show up there) and if not under which name I should have him look it up as?
