Kontrol S61 MK3 working on my Windows 11 PC but not on Windows 10 PC

P.S.

Also , one of the first 'sins' in connection with troubleshooting is assumptions ! And the statement "the MK3 not work with the Wins 10 pc" is not very specific either !

So I personally ought not assume that you e.g. "Verified the Hardware Status" , so if not make sure that you have !

Also , when trouble shooting then it's a wrong assumption to make that just because that on computer can correctly power a keyboard that then another can also , even if another device functions properly with the same port. If the keyboards works fine on another PC and you have tried more ports and port types on the other computer then the likelihood that it can be a power issue will be rapidly dwindling into almost nothing. But never the less, when all else (also?) fails then I think that if you have one and unless that you have not done so already then just to be thorough you ought to check also while having a proper power supply (USB-C PD) attached to the keyboard and still check with more cable and ports !

P.S. 2

I do not understand what "Video card is running Direct 3D 12.1" has to do with if Microsoft has updated the Win10 machine USB-C drivers for the N.I. keyboard or not ?

Ah ! , yes ! , I think I see where you are going ! You mean that as a buyer you have not properly been notified of USB-C requirements in the System Requirements section prior to purchase. And in fact then your computer ought not even require a USB port to use the keyboard (USB-C or otherwise) since N.I. do not say so in the System Requirements. Where N.I. only indirectly tells so by stating input and output ports ! (maybe the point of the given system requirements is that you maybe can use the keyboard as a midi controller with no USB-C port ?)

Well , sorry , all that you have to discuss with N.I. support or N.I. corporate.

I would still have to maintain the standpoint that I do not see what "Video card is running Direct 3D 12.1" has to do with if Microsoft has updated the Win10 machine USB-C drivers for the N.I. keyboard or not ? Unsuccessfully or not then as someone trying to assist/advice you to get the keyboard to function on the Win 10 machine then I don't think that it's furthering that to start discussing if N.I. sufficiently advertised System Requirements or not. Not even while I completely agree with you that the USB-C System Requirements ought to have been stated as part of the System Requirements !

Thank you for you (hopefully) understanding my personal position in this matter in connection with the question/matter at hand raised by you !

P.S.

Also in case you didn't notice then Matthew_NI who joined the discussion above is not just anybody in connection with all of the above discussion. Matthew_NI is listed as being Associate Director of Product Management, Kontrol and Maschine @ NI (previously advertised as Product Manager @ NI) , so you can be sure that any issue here has got the attention of even the "Product Management team" and I hope that you will at least appreciate that even if you have not been able to get a quick fix to your liking !

@DonSey , First of all thank you very much for returning and sharing solution. And also thank you very much for giving me (much needed) recognition/credit ! And congratulations on the cable investment and on getting your Keyboard to function with the Windows 10 computer also !

With respect to the cable ! : Then yes ! if you read the DataPro's USB-C Guide and FAQ and then starts to poke around on the site and the reads their articles on the USB4 and Thunderbolt 4 then you get exactly that impression that the passive Thunderbolt 4 cable (maybe even v.3 also) is superior to that of USB4 and one also finds out that USB4 is USB-C in both ends. So I seriously did consider advising you to go with a passive Thunderbolt 4 cable. But both is that rather expensive but also I am with respect to all of this at a great disadvantage/in a poor situation in as much as I do not own a computer with an USB-C port to test anything and no S-Series MK3 keyboard to test with anyway. I do have USB 3 on computer and USB-C units such as phones. But alas none of this helps. Further more then another recent hand-me-down were a "LogiLink UA0107" (External HDD enclosure 3.5 , SATA, USB 3.0) and the designer of that in my mind most have gone crazy the day that he designed that because it is designed with an USB-A 3 plug in the unit (where one normally always uses a B plug) so that makes the unit originally come with something as exotic as an USB-A 3.0 to USB-A 3.0 cable which I initially did not have. Me not being an idiot tried to find information about it and I finally discovered that the cable were not entirely backwards compatible (and that some pins are not connected) , over at DataPro , as you have now discovered that I am by now quite fond of , the cable is listed as "USB 3.0 Super-Speed A/A Debugging Cable" , anyway read about it yourself and weep that anyone will design an enclosure as LogiLink did with the above ! Anyway the 'some pins are not connected' part made me realize that there had to be a reason for that. But it also made me aware what possible damage could have been done had I started using a normal cable with some adapters. Hence ! : when I am not entirely sure with respect to cables then I prefer to wait uttering myself until such time that I am more confident about the proper use !

By the way , anyone reading a lot in this forum might have spotted me yesterday mentioning 'Startech' which were not by coincidence either. I am not knowledgeable enough on tech matters and do not have the wast product experience and the money it takes to get that that I am able to endorse Startech but to me they appear as a rather reliable brand for what appear to be an economy brand (compared) and lo-and-behold , it also over at Startech that they will feed you an interesting little article about USB 3.1 (which can use USB-C plug) and when one reads that then one might start pondering on the whole USB-C thing again !

@Matthew_NI , please disregard most of my rant about the Logilink enclosure and instead concentrate on the user (DonSey) cable issue above ! . I am just calling on you to have you consider if maybe N.I. could have saved itself from at least some troubles by distributing the units with a cable with better specifications !?
