PROFILE
En-wei Wu
En-Wei Wu developed and integrated support for the MediaTek MT7925 USB Bluetooth chip into the Linux kernel’s btusb driver, working within the geerlingguy/linux repository. By updating the device ID list in C, En-Wei enabled the kernel to recognize and initialize MT7925 hardware, allowing seamless plug-and-play operation for end users. This work involved driver development, embedded systems expertise, and close collaboration with hardware teams to ensure accurate device identification. The update improved hardware compatibility for MT7925-equipped devices, reduced user support incidents related to Bluetooth initialization, and aligned kernel support with current hardware shipments, demonstrating thorough end-to-end feature delivery.
