I bought the TP-LINK UB400 Bluetooth 4.0 Nano USB Adapter yesterday got it working perfectly, today I decided to stupidly download the driver for it
https://www.tp-link.com/au/support/download/ub400/#Driver which was the CSR Harmony Wireless Software Stack. Then once installed it lost my phone and dongle in bluetooth under windows 10 in Bluetooth and other devices settings, saying Dongle driver is unavailable and Galaxy s9+ Bluetooth is turned off.
In device manager it is under Other Devices as CSR_BTPORT_01, I tried reinstalling using CSR Harmony Wireless Software Stack but it says the CSR Harmony Wireless Software Stack.msi is missing, and search for it but it cannot be found. I have tried letting windows update search for updated drivers through update driver in Device Manager but Windows cannot find drivers for your device. Also I have tried setting CSR_BTPORT_01 as generic bluetooth adapter but gives This Device Cannot Start (Code 10).
So I just want to return to before I installed CSR Harmony Wireless Software Stack, I'm thinking I have to do restore point on windows 10 to earlier date.
Any help is most welcome.
