The software requires no installation. It runs directly from the extracted folder, leaving no registry footprint.
The primary purpose of this fix was to resolve a severe bug that occurred when the software was used to detect USB drives running on Silicon Motion SM3280 and SM3281 controllers. Older versions of ChipGenius, when scanning these specific USB 3.0 controllers, would trigger a fatal firmware error that corrupted the drive's metadata. For users who owned these specific, high-performance USB 3.0 drives, simply running a diagnostic tool could actually "brick" the device or cause it to lose its capacity. The v4.20.1107 fix patched this interrogation method to prevent the host-to-device handshake from accidentally issuing destructive commands to the controller.
. This specific revision was known for its updated database, capable of identifying the newer Chinese controllers that generic drives often used. The Extraction ChipGenius-v4-20-1107-fix.rar
Corrects errors in detecting Silicon Motion (SMI) SM3280 and SM3281 chips.

The update to version 4.20.1107 was not a minor improvement; it was a mandatory security and safety update. Previous versions of the software contained a catastrophic bug. When these older versions of ChipGenius were used to scan USB drives that used the or SMI SM3281 controller chips, the detection process itself would corrupt the drive's firmware, effectively "bricking" the device or causing the total loss of the flash drive's boot configuration.
The file ChipGenius-v4-20-1107-fix.rar is a compressed archive containing a specific stable version of ChipGenius. This lightweight, portable Windows utility queries the microcontrollers inside USB devices. Older versions of ChipGenius, when scanning these specific
: Added and corrected detection for Silicon Motion (SMI) chips, specifically the SM3280 and SM3281 series.
Once you run the program, it will scan all connected USB ports and populate a list. Select your target drive from the drop-down menu. The results window will then populate with detailed information:
