Summary

USB connection failures are often caused by a charge-only cable, a bad USB port, the machine not being ready, or a missing driver. A USB cable can charge a machine and still not carry data.

Steps

1. Try a different USB cable that you know can carry data.
2. Try a different USB port on the computer.
3. Make sure the machine is powered on and past its startup screen.
4. Install the manufacturer driver if the operating system does not detect the device.
5. Close other roasting software and reconnect in Rostoc.
