MediaTek Bluetooth MT7921
USB\VID_04CA&PID_3802&MI_00
What this hardware ID is
USB\VID_04CA&PID_3802&MI_00 is the identifier Windows uses for one exact piece of hardware. It is the reason a driver either fits your device or does not - Windows matches this code, not the name of your laptop. Here VEN_04CA is the company that made the chip (Lite-On Technology Corp.), and DEV_3802 is the chip model (MediaTek Bluetooth MT7921).
Every driver listed below declares support for this exact code, so any of them will install on your device. Choosing between them:
- Take one that lists your Windows version and architecture - the badges are in the last column.
- A newer release date is usually the better start. If the newest one misbehaves, an older release is a perfectly normal fallback.
- SHA-256 verified means we downloaded that file ourselves and published its checksum and contents.
