App Horizon

Horizon showing no device connected

I have tried to configure my usb through my Xbox360.
When I attach the usb in my Xbox and check into storage it shows
USB STORAGE DEVICE (also shows the storage)
when I go to device settings, it doesn’t give me any options like “CONFIGURE” or “CUSTOMIZE”, rather it shows the options, “RENAME”, FORMAT, CLEAR CACHE…
USB Device storage is shown and folder structure is shown in the XBOX, but when I put it in my computer, HORIZON doesn’t detect any device.
How can I configure through Xbox360 when it doesn’t give me an option to configure??
