Troubleshooting common issues

• Device not recognized: try different USB/serial ports or cables; check power; confirm drivers installed; inspect OS device manager for error codes.
• Driver installation blocked: disable driver signature enforcement temporarily (Windows) only if you trust the source.
• Incompatible OS: look for an alternative driver, use a compatible older OS in a virtual machine, or contact vendor support.
• Firmware mismatch: some devices require matching firmware — do not update firmware unless a driver and firmware are both confirmed compatible.
