Just for testing, I went to pickup a USB Bluetooth adapter. This system does not have an onboard Bluetooth adapter, and Bluetooth has not been installed on it before.
All I have done is plug in the adapter to a USB 2.0 port. The attachments are of the resulting install, which may take a few minutes to complete. I have not installed any drivers supplied with the adapter. I have checked it with my iPhone and it sees it fine.
Anyway, if yours does not look like this maybe we can track down the problem.
as i said earlier, only the generic bluetooth adapter is listed and NOT the ms bluetooth emulator or anything else ( ie my case does NOT match with the attached thumbnail ).
however, when i am uninstalling the generic bluetooth adapter ( ie uninstalling the device ) and then scanning for hardware changes ( from the right-click pop-up menu ) ms bluetooth emulator appears for a fraction of a second ( under the generic bluetooth adapter ) and then disappears - and only the generic bluetooth adapter remain listed. [ this is past behavior ]
ehow - how to restore bluetooth?
after reading the article i searched for "bth.inf.old" or "bth.bak". neither is present. only bth ( without the inf extension ) and bth.pnf is present. i changed bth to bth.inf.
then i uninstalled generic bluetooth adapter ( device ) and scanned for hardware changes. now it is showing as unknown device ( listed under other devices ) with error code 28. ( generic bluetooth adapter is not showing anymore ) when i am clicking the property of the unknown device it is showing as broadcom bcm2070...
The drivers for this device are not installed. (Code 28)
The installation failed because a function driver was not specified for this device instance.
To find a driver for this device, click Update Driver.
when i am clicking update driver windows automatically searches online, downloads and tries to install, and finally a message appears :
the driver installation file for this device is missing a necessary entry. this may be the inf file was written for win 95 or later.
btw, driver whiz and bluetoothdriverinstaller.exe could not be run as they have compatibility issues.
