hi there. my 6-core mac pro is standing outside of the control room in the studio where i work. all USB connections are made via USB extenders. everything works ok but the bluetooth dongle. since the magic mouse was not detected through the native apple bluetooth (to far away plus the thick walls) i decided to get an after market usb bluetooth dongle. this is working great, but everytime i restart the computer i have to disconnect de usb bluetooth dongle and connect it again and to link the mouse again. i guess there is a conflict between the native apple bluetooth and the usb bluetooth. i would appreciatte if anyboy could help me to solve this problem, since it's kind of annoying having to do this everytime i restart the computer. can i disconnect somehow the native apple bluetooth so it doesn't interfere the new usb bluetooth dongle?? thanks in advance!
