With some effort this might work for me, I have it reading one file name in a flash drive in a loop, not sure why it's looping,or not reading the others, but it's a start. If i can work this thing as I plan, I will add flash to my CNC machine as a serial feed, since that seems to be the way computers have gone. Too bad too, as the older computers only about 3/4 of the way supports USB, IMHO. I know the one at the shop sometimes does not become aware you plugged one in, so it's REBOOT !
