| Problem | Likely fix |
|---------|-------------|
| Device not recognized | Try another USB cable or port. Reinstall drivers with antivirus temporarily off. |
| Driver install fails with “hash mismatch” | In Windows, disable driver signature enforcement (Shift + Restart → Troubleshoot → Startup Settings → Disable driver signature). |
| Software says “No Valid Dongle” | Your SW is locked to a specific license; clone devices often need a patched .exe (use only if you legally own the software). |
| COM port missing but device shows as “HID” | You may have a USB-HID version – no COM port needed; just use J2534-compatible apps. | mechanic dx-480 software download
