good luck, I bought 4 different usb adapters for my fadal cause my office pc only had USB ports. only one worked. then I said screw it pulled out a rs232 pc(old one) and use it to transfer files only as its not good for anythign else. and it has a USB port. so I take the usb stick from my office pc to the shop pc.
The guys in the Fadal forum have said what brand to use of the USB adapters, and there pretty much spot on cause once I bought one of those it worked.
One of these days I am going to get a few new pcs and have my daughter network them in and into the machines. shes a whiz at that.
