I therefore went to Device Manager and un-installed it completely. I connected the device to the USB port and it showed up but was not working.
#Usb bluetooth csr 4.0 dongle driver windows 10 install
If you install these drivers in Windows 10 you are likely to have to un-install completely to allow this USB BT adapter to work. The CD that comes with it contains an exe for I assume Windows 7 - 8.1 operating systems. I installed on a Windows 10 laptop that in theory needs no drivers for BT devices. The product arrived with a mini CD and no instructions. So I decided to purchase from the least expensive vendor having first checked their star rating against the number of sales. This product you can find for sale from £3.45 to several times that price. So for the price, it’s a good dongle but the drivers just don’t seem to work well as Microsoft’s own, which would make me wonder to do like the packet says plug and play and leave the CD drivers out! TaoTronics 4.2 headphones paired fine and so did the Sony MDR 3.0 ones also. However, if you don’t use the CSR drivers and Microsoft’s own. When I added some TaoTronic and Sony MDR ones they found them fine to pair but once it tried to put the profiles together on found new hardware they just failed to install? Funny though they install absolutely fine it’s when you add your device such as headphones. Once the CD has installed the software and drivers your find on device properties it will say CSR Radio driver and on Universal Serial section another one is there. It doesn’t matter if you install the CD first or put the dongle in your get the same result either way that Microsoft’s generic drivers work and these don’t.
First off, the dongle itself is well made and excellent value but the brand chipset driver CSR (Cambridge Silicon Radio) just don’t cut it.
