I fear this alone won't be enough. We are discussing this topic here:
https://bbs.archlinux.org/viewtopic.php?pid=1038521#p1038521

Short summary:
The adapter seems to work in first but the log files say:
'localhost bluetoothd[1718]: Inquiry Failed with status 0x12'
while scanning.

From a short look in the Windows inf. file:
Fujitsu is listed there in a separate section called RAMUSBE031. There is also this "BCM20702A0_001.001.024.0023.0055.hex" file copied along with the driver, which is then referenced in the registry as "RAMPatchFileName". There is a long list of other 20702 adapters divided in those that need a 'RAM patch' or not. Maybe you could complete your list of compatible devices bases on this.

I own one of these Fujitsu laptops (E751 0x0489:0xe031) with the need for the hex file. If you want me to I can do more testing with to your guidance.

Thanks for your attention
Harvey
