Navigate to the Driver tab, and click the Uninstall button. Right click the device, and select Propertiesĭ. Under the Device Manager, locate Bluetooth Radios > BCM2070 or BCM20702Ĭ.

Hold down the Windows key, then press the X key. Uninstall the BTD-300/BTD-400 driver from the Device Manager.Ī. The steps below can be used to remove old drivers and allow Windows 10 to automaticalyl download and install the latest version.īe sure the USB adapter is plugged into the usb port on your laptop or computer. Out-of-date drivers for the BTD400 can cause issues with Bluetooth under Windows 10. Now I'm stuck with a completely useless dongle that Win7 won't install, and despite my extensive Google-fu, these drivers apparently don't exist ANYWHERE on the internet.In case you have not installed the adapter or its drivers before, please visit this article for new driver installation. The 'fun' part is that for reasons unrelated to this question, I no longer have the box/blister where the device came when I bought it, which had the disc with the drivers inside.ĭoes anybody here happen to have the same BT dongle that can facilitate me a copy of the files in the included CD for this device via ISO or some other way? I realize this is partly my own fault for not backing up the drivers from the included disc, but considering that I had saved the box with all its contents, even the instruction manual until my work room got 'cleaned up' by the maid, I did not even come close to suspecting I'd EVER lose that box. In my very-ticked-off-from-something-else state, I've no idea why I thought uninstalling the dongle would be a good idea, but I did, and now when I try reinstalling, the system DOES NOT recognize the dongle, and the Kinivo support site DOES NOT offer the files in the mini-CD that comes with the device. However, the system wouldn't find the headset, despite being right next to each other and both devices being discoverable. Today however, the thing didn't want to connect to my Bluetooth headset like it's been doing ever since I bought it, so I removed the headset from Bluetooth devices intending to re-pair it. I purchased a few months ago a Kinivo BTD-300 Bluetooth 3.0 USB dongle, and thus far have had very little issue with it. Machine: Acer Aspire 6676-7739g w/RAM upgraded to 8GB
