I have bought a TDK bluetooth adapter, so that I transfer files to and from
my PC and mobile phone.

It all works fine on my laptop, but not at all on my desktop PC. I plug it
inot the USB port, but it says "TDK bluetooth not found". I have tried
different USB ports but same thing. It gets power and stuff, but it just
won't fully recognise it on my PC. Like I said, the laptop works fine.

Any ideas please
