Was looking at the usb cable that came with the coby and curiosity got the better of me so anyways I took a 8Gig Kingston usb memory stick and plugged it in the other day. It mounted it and set up the andriod files on the stick. Just checked it with some files from the pc and they where read. It mounted in as sda device and can be unmounted. Not sure how big of a memory stick it will support though.
