i finally got my belkin usb adapter working (removed windows driver, etc) and am able to use DUN to connect my Toshiba Satellite to net via Sprint 650. The problem is that each time, in order to connect, I have to restart the adapter, re-pair 650 and the adapter, and only then can i get a BT connection going. I have to go through this process each time i want to connect...otherwise the 650 and Belkin adapter wont recognize each other even thought they have already been paired. Anyone have any ideas? Thanks.
