Moto L6's USB driver can be obtain from Motorola's web page:
http://direct.motorola.com/ENA/SoftwareUpdateSummary.asp?country=HKG&language=ENA&web_page_name=SUPPORT&strCarrierId=&strPhone=L6&strCable=Mini%20USB%20Data%20Cable
Run the update program and it will also install the driver for you.
But it is only the driver , still, you cannot transfer file to the phone from PC, to doing this, you need a paid program called "motorola phone tools" which you have to buy from motorola.
