The story of installing a Redsail cutting plotter USB driver
Summary Checklist

Issue B: “Driver cannot start. Code 10.”
- Cause: Power delivery conflict. RedSail plotters draw significant power. If you use a cheap USB hub or a long (over 3m) cable, the chip doesn’t initialize.
- Fix: Plug the USB cable directly into the back of your PC motherboard (not front panel). Use a shielded USB 2.0 cable under 2 meters.
