Help everytime when i open horizon and i want to install the game. Always says that 0 devices are found.

Are you using a flash drive or a hard drive from the 360? What’s the size?

flash drive

If I am not mistaken, you need to have the flash drive formatted to be an Xbox 360 Flash Drive. You can do that by inserting the flash drive into the 360, going over to settings at the far right, click on system, select storage, select the flash drive, and then configure the flash drive to be a 360 flash drive. It should work after you do that. Also in order to convert an flash drive to be a 360 flash drive, it needs to be at least 1 GB or greater.
