The reason this is happening is due to 2 factors: A) The configuration of the device itself. B) The misconfiguration of your computer’s OS. In order to overcome these two issues denying you from properly plug your android device into your PC, here’s what you’ll need to do:
Step 1 – Check to see if your device has the “MTP” (Media Transfer Protocol) option ticked-on, if not then go into: Settings -> Storage -> Menu Button -> USB computer connection and tick it. Now plug-in your device to see if it’s recognized or whether you can transfer files with no errors.
Step 2 – In case the first step wasn’t enough to do the trick for you, then you’ll probably need to install some additional packages / driver for it to work, to do so – download Google USB Driver and install it if you’re using Windows, if Linux is your OS then you might need to install libmtp and mtp-tools packages from your distro repository. Note: libmtp package can also be called libmtp9 or likewise so run a search for the package first (in Ubuntu simply type: apt-cache search libmtp).
Step 3 – If all else fails, then the best thing you can do is use a wifi app to access your files and make transfers between your device and your PC. There are plenty of apps available for download from Google play, my current personal favorite is WiFi File Transfer since it’s lightweight and simple.
