I am having trouble getting retropie version 3 betta for the raspberry pi 2 to download the roms folder to the usb drive. I have gone through the set up, enabled the USB rom service (326), made a retropie folder on the flash drive, and I’m leaving my flash drive in for well over 30 seconds. I’ve tried reformatting my flash drive; nothing. I tried re-writing retropie to the SD card; nothing. I have no idea what to do at this point, seeing as how all of the help videos say to just plug the usb in and it downloads automatically, which I’ve seen it do on other systems. Any help would be greatly appreciated. Thanks!
