First: This Bluetooth adapter is the best I've ever had. And I had ... well, three. 2 other products before this, and this one even now for the 2nd time - because it is so incredibly tiny that he was lost to me! So is no problem to leave him stuck permanently in the USB port. And despite its tiny size so a range - really good. Simple plan careful that he does not get lost ;-)
Therefore, I am in this to stay here because the previous all wanted somehow not quite - disconnections, some devices could not connect, and similar problems - an even smoking from one day to another completely off and was dead, even any recognition more.
Not so with this adapter: Since Day 1, he has no problem works, both of you. With all devices, Phillips Bluetooth receiver for audio system, smart phone [WP8 device, Lumia 920], and also Bluetooth gamepads that are meant for mobile devices.
Plug and Play! Until Windows now long ago brought out an update to the default Bluetooth drivers, which are also used for this adapter. This update should PAN support [Personal Area Network, nice treat] Add Bluetooth adapter, but somehow led to that this adapter from CSL, as well as some others like my research brought to light, no longer worked.
I have a detailed guide added as image, as the adapter can be set up correctly, it should only be recognized as a "CSR Bluetooth chip". In summary, it must be selected in the Device Manager, another driver for the device: > Update Driver Software Search> On Computer > Show list of device drivers > Generic Bluetooth Adapter > Install leave - and you're done.
This is, as far as I know, NOT PRODUCERS ATTRIBUTABLE - but Microsoft with Windows Update!
