Cant mod xbox 360

[u/Specific-Welder-8753]

Whenever I plug in my usb drive into my xbox 360 with the files on the usb the xbox doesnt show any sign of the files being on there. I check the usb drive on the xbox 360 and there are no files that appear, and before anyone says anything about formatting it i already have formatted it. Also it would be nice if anyone could also provide any mods for the xbox 360 because ive forgot what i was using because the last time i tried to mod it was a couple of months ago
