I`ve been using a bluetooth usb dongle for my pc for a long time and it has been working smoothly with my previous phones(6630...etc) but cant get it to work with my N95-1!!(both the dongle and the n95 recognize eachother but cant pair or transfer files!! and the strange thing is that my n95 can pair,send and recieve files with other bluetooth enabled phones but NOT with my pc!)
i`ve tried to install that dongle on my other computer (laptop) and got the same result!!
Are you using windows xp?
Do you have a third party driver for your USB dongle installed?
If you have a third party driver installed, remove it and let windows xp install the standard driver. I've done this and it works fine, can control the pc with the phone as a mouse, transfer files by right clicking and selecting "send to> bluetooth device" etc...
