I have had no luck connecting to new BLU R1 HD phone to my Windows 10 desktop via USB.
I have tried 2 different USB ports & 2 different cables (which worked for my old phone).
I have "data transfer" enabled on the phone using MTP.
Nothing shows up in File Explorer, but I do see a new unknown device appear in the Device Manager under "Other". Properties show no Driver installed, but Update Driver s/w appears to find drivers locally in C:\Windows\INF or by searching online, however these fail to install with the same error.
The drivers for this device are not installed. (Code 28)
A service installation section in this INF is invalid.
To find a driver for this device, click Update Driver.
Any help will be much appreciated!
