If not open DM and on the left click, options>connections choose BT and check enable BT and also check auto switch to USB when USB is connected.
Then click connect see if that works...
I have the same challenge. The BT connection options on the DM are greyed out. I'm guessing it shouldn't be. Any suggestions or thoughts as to how to fix this? Thanks!
I 've got the same problem (BB 8800, laptop HP NC6400). Other devices like Nokia, Ipaq use bluetooth but desktop manager not (checkout box is grey).
Help me.
