Im having problems with the USB Flash Units...
I have tested 5 non-label usb flash units, but all of then dont work...
A couple of days later, I found my old "Kingston DataTraveler DTI 1GB USB 2.0"... but this doesnt work neither...

So, I try to buy some of the listed USB Drives on the compatibility list... Finally found a cheap one via eBay, im talking about the
"Sandisk Cruzer Micro U3 [USB2.0] 2048MB Flash (SDCZ6-2048) (tested after removing U3 partition)".

The Sandisk Drive arrived today, so Ii formated the USB, and take off the U3 software, i also fotmated following the steos of the "USBFATXFormatter".....
But when i plugged into the Xbox using a USB Female cord, my Xbox keep saying "Unit isn't functioning, it may be damaged"....
Please help me out... what else can I do, when this 2 USB Flash, are in listed as compatible but are not working.
Sorry for my english.
