Once in a while I get an error message when I boot up usb loader gx and cfg loader. The usb loaders aren't able to recognize my 8 GB usb drive, (this doesn't happen all the time) there is a 30 second countdown and nothing happens. To fix this I have to disconnect and reinsert my usb drive during the countdown. Does anybody know why this happens ? I have check on the usb drive compatibility list and my usb drive is compatible.
