Mine works with every memory type i have including 3 different USB memory sticks as well as a cheap memory card reader with a 8GB SDHC memory card in it.
I think he needs to concentrate on the media player and photo viewer so songs & pictures can play back to back.
He's working on-

Directory/File Manager style UI - Version 3
Share (to GMail, Drop Box, etc.) - Version 3.1
Better Photo Viewer and Music Player
