Looking at the details in your post I have little to work with. But let me share. On Windows xp, vista and 7 my usb bluetooth adapters plug in and just work. I didn't have to install drivers.
And these are those 6 buck adapters you see all over!
I have installed bluetooth drivers into my my Dell Inspiron n5010 laptop.But during installation it cannot able to install some files.Can any one give the solution for this ASAP
