Chipgenius V4.21 [exclusive]

ChipGenius v4.21 is a specialized diagnostic software utility used to identify the hardware details of USB-connected devices, such as flash drives, external hard disks, and card readers. It is particularly favored by technicians for identifying the specific microcontroller (USB controller) flash memory chips inside a device. Key Features of Version 4.21

Device Specs: Protocol version (USB 2.0/3.0/3.1), serial number, manufacturer name, and current processing speed. Features of Version 4.21.0701

  1. USB Standard Descriptors – VID, PID, iManufacturer, iProduct.
  2. SCSI Inquiry Data – Vendor, Product ID, Revision.
  3. Controller-specific commands – Many controllers support proprietary commands (e.g., Phison’s 0xEE opcode) that return chip ID and flash layout.
  4. Flash ID extraction – By sending READ ID (0x9F for SPI NOR, 0x90 for NAND) through the controller, it obtains the flash’s manufacturer and density.

Interpreting Results: I can explain what specific "Controller Part-Numbers" mean if you have a report. Chipgenius V4.21

Detects the type of NAND flash memory used, including the manufacturer (e.g., Samsung, Hynix, Toshiba) and the Flash ID. Hardware IDs: Displays the (Vendor ID) and
