Problem solved. Thanks for the instruction. It worked for my compaq nc6400, windows 7 ultimate. I solved the same problem with unrecognized BT devices like this: I found that these devices are suspected to have Qualcomm Atheros chipsets.

So I looked for software for that chipset. I found great driver on and chosed driver Qualcomm Atheros BlueTooth driver Version V8.0.1.318. Than you can choose silent installation via 'install' file or regular, prompted - with 'Bluetooth Suite 32 / 64'. I choosed silent installation. After 3 minutes my device manager firstly showed 10 new unrecognized devices but every next few seconds it was discovering new device and making it described and wroking properly. After next few minutes ALL my unrecognized devices were correctly installed and placed in Windows device manager. Looking for driver - be carefull, because there are few pages which calls drivers as 'Qualcomm Bluetooth Suite' but in fact this is their own fake software installing any driver recognizing stuff from that companies.
