I also recently purchased a similar (or same) device (CSR v4.0 bluetooth dongle), and have a laptop with a Windows7 Home Premium 64bit operating system.Īlthough a 'plug and play', it still required installing the driver software from the mini-disk that came with it, which contained the Cambridge Silicon Radio Ltd. Hi, experts, I have just purchased a new bluetooth v4.0 dongle (brand should be cambridge silicon radio).Īfter I plugged to my labtop (win7 home premium 64bit), windows 7 detects it as generic bluetooth radio.
