ChipGenius.exe→ Run as Administrator.- Why? Low-level USB access requires kernel permissions.
- Insert the target USB drive.
- Click the "Refresh" button or press F5.
- The results appear in a table. Look for:
- Device Info (VID/PID)
- Chip Part Number (e.g., Alcor AU6989SN)
- USB Device ID (for driver searches)
1.1 Overview
ChipGenius is a proprietary Windows-based utility designed to query USB devices (flash drives, card readers, MP3 players, external HDDs, etc.) and extract the actual controller chip information, even when the device’s vendor name and model have been spoofed or corrupted. The “v4.21 Fixed” release refers to an unofficial but widely circulated patched version of the original ChipGenius 4.21, intended to correct specific bugs and improve device detection. Instructions
1. Reviving “Bricked” USB Drives
When a low-level format fails or a firmware update interrupts, the drive shows 0 bytes. ChipGenius v421 fixed is often the only tool that can still extract the controller ID in this state, because it bypasses Windows’ logical volume manager.
4. Instant VID/PID Lookup Database
The fixed version includes an embedded chipgenius.ini file with over 2,300 known VID/PID pairs, making it faster than online lookups.
