Kontrol S Series mk3 keyboard long USB-C cable

Quote : "I can and may resort to a USB-C to USB-A high quality cable to resove the problem, but I then have to convert the A end back to C, since both receiving ports are in USB-C configuration."

This is a no go ! The USB-C to USB-A cable were solely a suggested fix if you had an available USB-A port on the computer.

If you have only USB-C ports available on the computer then the route that you need to take is using a self-powered USB-C hub with PD as go between keyboard and computer. and then still add the USB-C PSU with PD on the keyboard power port. Remember that cables in the connection chain from keyboard data port to computer must be certified to data connection and what used for the power port on Keyboard must at least be certified for USB power delivery and same goes for the PSU (again choose minimum 20W).

On the subject of Thunderbolt cables then if using that then it must be passive cables !

N.I. and support do care , you can ask N.I. support also if you want (I am just another user here and not an N.I. employee) , and while I don't know all the varying rules for different countries then my guess is that if you got a copy of the original purchase receipt then the keyboard most likely is still under warranty. But you have to check that for yourself !

At this point, to avoid any discussion misinformation I will post the what Matthew_NI stated information ! :

To be very clear, and to avoid any one opinion becoming misinformation, I'll re-state what has been said in various places:

   As frustrating as this is to you, it is also to us.

   This issue is specific to the USB-C implementation on certain computer models.

   This issue is not specific to the peripherals themselves.

   This issue causes the communication in the protocol to essentially break, thus data is dropped.

   This manifests as various symptoms, depending on the peripheral. For Kontrol S MK3, the dropped data can interrupt a firmware update, or controller -> DAW and/or controller -> Plug-in sync.

   The issue can appear at random, frequently or infrequently.

   Using a USB-C hub interrupts and bypasses the problematic communication specific to the chips used in the USB-C implementation of affected machines.

We can highlight and advise on workarounds, should a customer be affected.

We can, and have, reported this directly to the manufacturers of affected models. So have many other manufacturers of peripherals.

They can, and have, fixed it in newer models, but of course there exist affected models in the market that will forever be subject to the workaround.

We cannot do any more than this. I'm sorry that some of you choose to blame us. I recognize that it's deeply frustrating, but I cannot change the facts of the matter that I've outlined above.

MK3 has two ports:

1) For simultaneously data and power

2) For auxiliary power if the first port is not able to provide adequate power (e.g. a USB-A port)

These are not two separate issues.

This narrative simply isn't factual. I know how frustrating this is - but please recognize that the shortcoming here is specific to the USB-C implementation in certain hardware, and not the peripherals that are affected by the shortcoming.

As I've stated - it is to do with communication protocols in the chip breaking down, which can affect the transfer of whatever's coming down the pipe (USB-C cable).

Also, we are not talking about a lot of cases. We are talking about a small number of cases handled either here in the forum, or via our customer support channels, or both. The number of unaffected customers is exponentially larger.
