    im literally losing my mind here so my Ethernet adapter reports Code 43 now.

    USB Audio Device Properties

    USB Audio Device Properties
Device status:
This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

    Ive read that Code 43 can mean the hardware failed, but teh timing with teh Gigabit Ethernet USB 3.0 Driver update is too perfect. My work PC is offline until this is fixed. Id like a solid plan: what to test, what to download on another device, and what to install in which order. Any help is hugely appreciated. seriously need help here 😭

    yeahhh on another device, download teh network driver from the PC or motherboard makers support page, copy it via USB, and install. Use pnputil /add-driver <folder>\*.inf /install if teh package only contains INF files.

    Code 43 means the device reoprted a failure to Windows. First do a full power drain: shut down (Shift + Shut down), unplug for a minute (remove the battery if possible), then boot. Network chips can get stuck in a bad state that only a power cycle clears. worked for me anyway 🤷

    oof if the adapter keeps failing on every driver and after a power drain, test it in antoher PC if possible, or use a cheap USB adapter temporarily while you arrange a replacement or warranty.
