Displays the maximum current (in mA) drawn by the device, helping diagnose power-related hardware failures.

Version 4.21 includes an expanded database of USB controller chips, accurately identifying newer USB 3.0/3.2 controllers alongside legacy USB 2.0 hardware.
If a flash drive shows "No Media," "0 bytes capacity," or Windows asks to insert a disk, it usually means the controller firmware is corrupted. ChipGenius provides the exact controller model (e.g., SM3257ENBA), allowing you to search for the specific "MPTool" (Mass Production Tool) needed to re-flash the controller and bring the drive back to life. 2.
