Recently I bought the new Acer Iconia Tab A501 android tablet, and now after few days I can see that there are problem with the USB. The problem is when I connect with the USB, at that time I cant see all the files or folder contains in that USB. For example if I am having files within folders. Here I want to upload the folders, but when I connect it at that time I see only the folder not the content of that folder. So what can I do here with my Acer Iconia Tab A501? Is that problem is related with the Acer Iconia Tab A501 os it is caused by the USB only? Please suggest me in this case.
