If you want, I can:
| Symptom | Cause | Official Fix | |---------|-------|---------------| | “Driver not signed for Windows 10” | Old driver lacks SHA-256 cert | Install via OR disable signature enforcement temporarily (not repack) | | Device shows code 10/28/43 | Corrupt driver or missing registry | Use USB\VID_0A12&PID_0001 (generic CSR) fallback driver | | No driver after Windows update | Microsoft replaced it with generic | Uninstall generic, force reinstall from manufacturer’s last official EXE | | Repack “works” but has issues | Repack actually uses a CSR driver spoofed as ISSC | Tells you the adapter is likely a CSR8510 – install CSR Harmony driver instead | Bluetooth Isscbta Driver Windows 10 REPACK
