Yesterday I was able to connect my Tab to my Win XP PC using the USB cable. I was able to transfer files without difficulty. But, some how I must have changed a setting on the Tab and the Tab is no longer recognized by any of my PC's. I think it is a Sync setting that was changed. Now, when I connect using the USB cable, the PC says " Found New Hardware MTP" What settiing do I need to change to get the PC to recognize the Tab?
