✅ Officially supports Windows 11 22H2+ and Windows 10 (x86/x64).
✅ Includes digitally signed drivers (no more F8 + “Disable Driver Signature Enforcement” in most cases).
✅ Adds CDC ACM class support for better serial communication.
✅ Fixes the “Code 10” error that prevented device enumeration.

| Problem | Solution | |---------|----------| | Driver installs but phone not detected | Use a USB 2.0 port (no hubs). USB 3.0 often fails for legacy SPD devices. | | “Device cannot start (Code 10)” | Uninstall the device (check “Delete driver software”), reboot, reinstall. | | Driver signature error | Redo Step 1 – disable signature enforcement again (Windows updates re-enable it). | | Phone shows as “Android” | That means you’re in MTP mode. Turn phone off, hold Volume Down (or Volume Up) while connecting USB to enter download mode. |
