It should just work. Check device manager if it’s recognized and not have a “?” on it’s icon. If that’s the case, reinstall the default mtp usb driver.
In Settings | Developer Options: Developer Options ON | USB Debugging ON | Select USB Configuration MTP
(In Settings, touch Build Number seven times to open Developer Options, then you set Developer Option ON. That is the SECRET HANDSHAKE in the Android world.)
For those who had a similar problem, I post the solution.
Go to My computer, right click, Properties, Device Manager, right click on the unrecognized device, update drivers, choose driver manually, audio/video drivers, MTP USB device.
