Just about anywhere computer accessories are sold. Type A to Type B connectors, just like most printers, scanners, etc. If you have a USB printer, etc., you can use the same cable, since you won't have to leave the pedal connected very long. Wouldn't have to buy another cable, either.
Yes, I use the USB cable and which is really working for us. I use the printer and which is really helpful for us. And I use the printer and if I have an issue with printer then go to the printer repair near me to solve the problem. which provide good service.
