So im using usb loader gx 3.0 1260 and using ios 249 and tried 250 also and when i use my 16gb sandisk flash it works but i am trying to use a usb 3.0 card reader with a 64gb micro sd but freezes at the usb initialize screen. The anker 3.0 card reader says its completely backwards to usb 2.0 and reads all card formats even xc. I also formatted it to fat32 with EaseUS then format to wbfs for games and nothing. What is wrong with it always freezes on usb devicescreen but not my small 16gb ones??
