I just bought the TP-LINK UB400 Bluetooth 4.0 Nano USB Adapter
I have Win10, so I put it into a USB 2.0 Slot - but no joy. In the meantime I tried it on about 6 different USB 2.0 and 3.0 slots, same result:
a) In the Device List, I can see the following appearing when I plug it in: Universal Serial Bus Controllers: CSR BlueCore Bluetooth
b) There is NO bluetooth section in the device manager. So the system has not yet regonized, that there is bluetooth enabling hardware plugged in.
c) When i go to Settings, bluetooth and other devices, I can see it under "Other devices". It simply says: dongle.
What I tried:
1) I right clicked on CSR BlueCore Bluetooth, then update drivers, search automatically. I already have the latest version. If I got to it's properties, it says:
Driver Provider: Cambridge Silicon Radio
Driver Date: 26-Oct-12
Driver Version: 18.104.22.168
2) I've tried "remove" from the device list, then unplugged it, and plugged it in again: Everything is back the same like I describe on 1)
3) Like I said, I tried different USB Slots. Some on my USB Tray in the front of the PC, but also some on the back of the tower. USB 2/USB 3, tried both.
Thanks for the help.
