Small 64 KB binary from ASUS whose name points only to USB 3, most likely firmware for a USB 3.0 controller or hub chip rather than the main system BIOS. The name does not state the laptop model, board number or controller part, so identify the actual chip on your board before using it. Controller firmware of this size usually lives in a tiny serial EEPROM or SPI flash next to the USB chip, and a corrupted copy can leave ports dead. Back up the existing chip and confirm its capacity matches 64 KB before reprogramming.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
