Ok guys here is what I did.
I did not want to purchase a action pack.
Therefore I used a Lexar 256MB Fire Fly USB drive.
You can find these at walmart.
I then used UBSView to read the firefly USB id info
I made two simple edits to the first line in both copies of xbreader.inf
THERE ARE TWO COPIES OF THIS FILE TO EDIT
found C:\\program files\\Datel\\Action Replay XBOX\\
One is in that root dir the other is in
C:\\program files\\Datel\\Action Replay XBOX\\Drivers
Open the file in notepad and go down to [_Devices] on the first line you need to make edits:
For the fire fly here is what it should look like when done
Save the file, be sure to edit both files,
I have a xbox - usb cable, I plugged that into the xbox and let it erase/format the usb drive.
in xp windows I had changed the usb drivers for the thumb drive and done.
I was able to write to the usb drive via action pack.
Yes I am up and running XBMC
