I investigated this with a NETGEAR A9000 (0846:9072), see [1]. MediaTek's Windows driver for the A9000 (mtkwecxu.sys 5.3.0.3230) controls the LED using UNI command 0x2a, with GPIO 8 and a TLV (tag 1) specifying the LED state (on/off). Sending the same command from mt76 works with the firmware from the Windows driver package (MT7925_E1_ASIC_ROM_RAM_CE_2249_CCN10_USB, 20250424), but not with linux-firmware builds (CE_2249_CCN16, tested with 20231227 and 20260813). The latter return status 0 but do not change the LED state. All 16 MT7925 firmware releases currently in linux-firmware are CCN16 builds. Could you clarify: 1. Can GPIO-based LED control be enabled in the linux-firmware build for MT7925 USB adapters? 2. If not, what is the intended way to control these LEDs on Linux? 3. Is GPIO 8 common to all MT7925 USB adapters, or is it board-specific? I have a small mt76 patch that registers the LED for MT7925 USB devices and sends this command. I will submit it once firmware support and GPIO selection are clarified. [1] https://github.com/morrownr/USB-WiFi/issues/731 Thanks, Josef
