Can't update the firmware for KONTROL S49 N // Doesn't seem "to mount"

PrettyPlease

Hello,

Sorry if that if already asked :
I tried to folllow protocols.

I recently bought a NIS49 Keyboard, new one.
It seems I'm stuck at the firmware update manoeuvre.
Nothing shows up in the Windows panel : See image.
I must have missed something.

Earlier on, I directly fell into error messages as, in order :

- Low power supply (I found a new port and it went out...)

- Update by entering serial (which was already done in native access, all right).

I verified my version of windows : Latest.
Version KK installed : Latest
Version Native Access : Latest.

Then, Step 5, right here : I tried to update the firmware as I don't see it (KOMPLETE KONTROL S88 DFU) in the USB serial BUS universal in the windows drivers panel.

That's where I guess I am blocked : The keyboard doesn't seem to be recognized, and "don't mount".

Now, this might be important.

I've lost my mail account recently.

So : I don't remember my password of my NI initial account.

I created a new one, and did all these operations with the new one :

It recognises some (not all : I have to verify) the extensions I have, I downloaded the Hardware Connection Service, I installed it.

Maybe, that's where the problem comes from : Serial :
I Might have to fill this up in my initial account :

If that's the case : How can I get it back ? I used to remember the password by heart, these days I don't...

Here's a screen shot...Or two...

Thanks for the help if you can give me directions.

Sure enough, needless to say, I'm stuck and frustrated

Thanks
