ive got 128 mb usb stick working on it ,
whats the max gb of usb stick or usb hdd you can use with this gadget ,i mean can i attach a usb hdd to play files,music pic movies or games of it ,cause the hdd in the xbox is only 10 gb

How many times does this question have to be answered? Did you even bother to search?

4GB.

just to add..
your not going to be using it for much even if you do try to use it for what you wanted too..

its the slowest usb you have ever seen..
you should strongly concider getting a bigger hard disk

thanks for the clarification
i do have a bigger hdd will do it this weekend
