Got my adapter cable today (About a week from Hong Kong). I plugged both an sd card reader and a thumb drive into my 8G2 and both worked. I played a couple of video clips and transfered a couple of APK files to both my interal and external sd cards.
No settings have to be changed. I plugged the device into the adapter cable then plugged the cable into the 8G2. The minute I plugged it in the notification bar said that the Mass Storage Device was being disabled. I went to my file manager and had full access to the contents.
I couldn't find any place to unmount the usb when I was finished so I just unplugged it. I was notified the the usb port had been unexpectedly disconnected - but no harm was done and I was able to connect to my PC with no problem.
I have a feeling that this would also work with the 7G2 (not the "C") since they are running the same OS. Anyway here is a link to the place I bought my adapter cable.http://www.ebay.com/itm/ws/eBayISAPI.dl ... OU:US:1123
