• Follow the “Have Disk” method as above. After installation, you’ll see a new COM port under “Ports (COM & LPT)”.

• Wrong driver / counterfeit chips: If the found VID/PID corresponds to a chipset but driver fails, try alternate vendor drivers or an older driver version (especially for PL-2303 counterfeit variants).
• COM port conflicts: Change COM port number in Device Manager → Port Settings → Advanced.
• Driver signature enforcement: XP will allow unsigned drivers but prompt—accept if you trust the source.
• RNDIS/network adapters not appearing: Install Microsoft updates for USB RNDIS support or use the vendor-supplied INF. Reboot after install.
• Device works intermittently: Try a different USB port (use USB 2.0 ports—XP-era devices may not handle USB 3.0 well) and use a short, good-quality cable.
• Reinstall: Uninstall the device from Device Manager (check “Delete driver” if offered), unplug, reboot, then plug back in and reinstall.
• Virtual COM app issues: Ensure the application is configured to the right COM port and baud rate. Use a terminal program (PuTTY, Tera Term) to test basic connectivity.
