The most common problem when attempting to load patterns is that your USB does not have a patterns folder on it, or that the pattern files are not in the patterns folder. If you are getting this message, then you don't have a patterns folder:
Waiting for USB Drive
Unable to open patterns directory, trying blocks
Unable to open blocks directory, trying quilts
Unable to open quilts directory
No patterns of quilts were loaded
You will need to create a folder names patterns (all lowercase) on your USB drive and put all the pattern files into that folder for the IQ to recognize and download the files.
