Compatible USB cable for KK A25?

There was an error rendering this rich post.

So I know I need a USB cable with a type B connector for the A25, but I'm presuming that the other connector is type A from the pictures I've seen of NI controllers on eBay and Reverb.

I saw this as well: https://support.native-instruments.com/hc/en-us/articles/210293725-Choosing-the-Correct-USB-Cable-for-Your-NI-Hardware-Device

I've found some cables with 24AWG, but that's the most I can find.

My questions 1) 'is there a brand of cable that meets those specs that y'all can recommend?' and 2a) 'will it make any difference if the other end of the connector were USB-C' or 2b) if the cable is USB 3.0 is there any appreciable improvement in data transfer speeds?

Those last 2 questions are b/c I have seen both these types of cables at different prices, but I can't confirm they match the recommended specs or if I'd be spending more $ for no benefit.

This is my first MIDI device so I appreciate any info in this matter, thank you!

2a I have a DigitalLife USB B to USB C cable which works perfectly. I’m sure almost every other brand will work too… it’s easier to find working ones than being so unlucky to find one that has issues. I have a ton of USB B cables lying around and never found one that doesn’t work. True that they are almost all from musical devices… Of you already have some USB B cable, test them. I’m sure they will work.

2b If you need to use an USB C port on the other side to connect the keyboard, you can use an USB B to USB C cable without any problems. I would even say that it is better than then having to use an USB A to USB C adapter.

2b USB 3 will not make any difference in the case of MIDI

@LostInFoundation thank you so much for your advice!

THe other end of the connector doesn't necessarily have to be type C, but I have limited I/O on my laptop. I have 2 USB-C ports (of which one is Thunderbolt 4 capable) and 2 USB-A ports. Often times there is just one C port available as that is the path for charging, so I would have to either unplug the A25 or my audio interface.

Of course I could always get a hub, but if there were no difference in performance I could use those type A ports for the A25 and use the other free USB-C for my interface. That's why I was curious about USB 3.0 as well, b/c if the top data transfer speed is capped by that 2.0 standard, I figured type A would effectively be the same as type C. That's just my assumption as all the replacement cables I've seen as replacements are type A on the other end.
