I have just purchased a Prestige 7L-4.1 from Walmart (I see a few others have also). I'm slowly going thru a learning process of how to operate this beast and maybe in tame it. I have downloaded apps, watched a movie with my headphones, explored the internet. Now I wish to establish connectivity between my PC and my new tablet. This is the process I went thru. With the tablet off, I plugged in the USB to the Tablet and the other end to the PC. I then turned on power to the tablet. The PC recognized this and started adding drivers. These are the drivers added: 1) USB Composite Device 2) USB Mass Storage Device 3) Alcatel Android ADB Interface 4) USB 2.0 Flash Driver 5) USB 2.0 Flash Driver. When I look at my Windows Explorer I see 2 new drives which I think are items 4 & 5 above. When I try to access them it tells me to insert a disk. I looked in Device Manager and this Alcatel Android ADB Interface is under the heading of Android Phone. Can someone tell me if this is the proper driver to interface my PC with my new android tablet??? Thanks for your help.
