Cant find USB device

First off, Hey all, Merry Christmas.

I have taken these steps to try and make Horizon find my USB device.

-reinstalled horizon, updated to newest version
-formatted 3 different USB sticks with Xbox 360 to try and see if faulty USB (by format, used format option on dashboard, not sure if this means configure or not)
-I have uninstalled USB device drives for the USB sticks I want to use and then put the USB’s back in to regain them
-I have used 2 of the 3 USB before for Horizon, and they worked perfectly about 3 months ago, they all are 4+ GB
-On Horizon program, i try to click on connect device but it literally does nothing at all
-I have tried this on 2 PCs still no luck.

PLEASE HELP ME, MY DAY OFF WORK AND LITERALLY SPENT ABOUT 3 HOURS TRYING TO FIX IT.

I have now fixed and resolved the problem by downloading Horizon from another Link posted by another user from a different thread, so thank-you ‘Zodiac’ from this following post: https://www.horizonmb.com/threads/172416-Horizon-USB-Devices-and-the-New-Dashboard
