If you have a working version, here is the critical data it provides:
Many USB 3.0 drives from 2014-2018 use Phison PS2251-03, PS2251-07, or SMI SM3267 controllers. The fixed v4.21 identifies these with 99% accuracy, including the exact firmware version.
Note: Always verify independently.

ChipGenius v4.21 Fixed is a specialized utility designed to identify and extract hardware details from USB devices. Developed by hit00 and maintained by the mYdigit community, this tool is the industry standard for diagnosing "dead" or unrecognizable flash drives by revealing their internal components. Core Functionality and Features
Unlike standard system tools, ChipGenius interacts directly with the USB controller to provide data that Windows Explorer cannot see. Key features of the v4.21 version include:
Deep Hardware Identification: Extracts critical data such as the VID (Vendor ID), PID (Product ID), Device Serial Number, and the specific Controller Model.
6-Byte Flash ID (FID): A specific improvement in the fixed/updated versions allows the tool to output a 6-byte identification code for flash memory, providing better accuracy for modern high-capacity chips.
Fake Capacity Detection: Useful for verifying if a drive has "spoofed" capacity. It compares the reported size against the actual physical capabilities of the detected memory chip. Note: Always verify independently
Portable and Lightweight: No installation is required; it runs as a standalone executable.
Enhanced Chipset Support: Includes updated support for the latest chips from manufacturers like Alcor (AU6989SN series) and Chipsbank (CBM2099/CBM2199). How to Use ChipGenius v4.21 Fixed for USB Repair
