I've had 1 usb stick that worked in my old xp laptop and the embroidery machines, but wouldn't in the PC. Now a new stick works in my new PC, but not in either of my machines. (Brother and Pfaff) so I can't help. I did find that the connection points on the first stick were not quite as long as others that did work, and it also works in the hub I now have for an external hard drive.
