I have iMac 17" Flat Panel Mac OSX 10.4.10
I use D-Link Bluetooth DBT-120 adapter. It worked fine for last two years.
Now I get "Bluetooth: Not Avialble" message with broken Bleutooth Icon at top right hand corner.
I see LNK and PWR lights on Bluetooth adapter are not illuminated. I tried attaching adapter to different USB ports but still no use.
Is this a hardware issue or software issue?
Do I need to buy new Bluetooth adapter?
