Plugged & unplugged a few times. I sent email to Axiom over a week ago... Crickets... :-( Its getting old. Not a year old and minimal use I'd expect better,,
If you're not loading the file from the USB stick onto the controller before running it, you should be doing that. Once you have done so, no further communication between the two is required and any issues in communication with the USB stick are not a factor. These things ARE picky about what USB stick you're using.
