Bluetooth and USB storage issues with XPS 13 2015 9343

Mine's a 2015 Dell XPS 2015 edition (9343) .

Everything seemed to be working just fine until the last month . The moment I try to pair a Bluetooth device ,  it gets disconnected the moment its successful ( the pairing) .

Also , any USB storage that I connect , the laptop somehow recognizes it as 'Local Drive G:' and I get the following message :

" G: is not accessible.

The Request is not supported "

Any suggestions as to what I should do ?
