drivers won’t matter. If the device doesn’t show up in Device Manager, there’s a fundamental issue that the USB device doesn’t appear to the USB bus even before it gets presented to the OS. If there’s no matching driver, it’ll just appear with an exclamation mark. This is one reason I turn sound on and listen to the connection sounds - if you get no noise, it’s not even getting power from the bus; if you get a high-low noise you are taking power but not presenting a device, and if you end up with a low-high noise you are presenting a USB device to the OS. You might get repeated high-low which can be signs a device is trying to draw too much power or has a short. All great additional diagnostics
Sure. When things work, this will happen - but if you don’t try to get into bootloader mode it should also appear as a device, and it’s unlikely getting into bootloader mode will get you any further if you have a USB connection issue in the first place.
hope these additional steps help, at least they may help show your next area of focus (and until your devboard arrives )
