Can't transfer data to PC

Try another USB cord, just in case there's a problem with it. Also try restarting the phone and the PC.

 

Not sure about the current issue, but you might consider just enabling sftp on your computer and installing a sftp client on your phone. (Many file managers already have this capability) Hassle free file transfers from anywhere in the world.

 

Some Android devices require a driver from the manufacturer to be installed. Make sure the device is awake during transfer.

 

what phone do you have?

 

Have you tried wireless transfer with wi-fi?
