List of drivers for other devices O2Micro

This section collects official O2Micro drivers and firmware for common embedded controllers and card-reader hardware used in notebooks and USB multi-card adapters. You’ll find downloads for SD/MMC and microSD controller drivers, USB card reader packages, power-management/EC utilities and legacy laptop controller updates. Each entry lists supported operating systems, file size and release date to help you match drivers to your device.

To install: pick the package that matches your hardware ID and OS, download the ZIP or EXE, then run the supplied installer or update via Device Manager. Many packages include signed installers for Windows 7/8/10/11; some older models require legacy installers or manual INF updates. Check compatibility notes and version history before installing, and create a system restore point. If a native Linux or macOS build is unavailable, community drivers or kernel modules may offer support—see individual pages for links and step-by-step instructions.
