Is there a program for remapping keys from a keyboard connected to a specific USB connector?

Question

Hotkeys

There are two keyboards. One is normal, and the other I want to use as a quick panel for macros. The problem is that if I assign some kind of macro, let's say to the Z key, then it works regardless of which keyboard I press this key on. Over the years, many different keyloggers have been released. Maybe someone knows where it is implemented out of the box?

UPD. I found an article where they do something that I want, but I didn’t want to bother with installing a lua editor to intercept hooks https://rmmedia.ru/threads/133889/

So I found a simpler option for me. https://github.com/agabor/RightKeyboard/blob/master...- RightKeybοard simply remembers which keyboard has which layout. Accordingly, you can set some specific layout on the additional keyboard, such as Greek, and use any program to create and manage macros. There are only two minuses in this solution:
1. A third layout appears, which is not needed in a normal situation, i.e. switching between Russian and English layouts is difficult if you do not use specific keyboard shortcuts to switch to the desired language. Perhaps simply programming the key change combination through, again, an external interceptor, which will change the language instead of the standard Windows tools, will help here.
2. And the second, more fundamental minus. The keyboard type is determined after pressing, i.e. the first press on another keyboard will call up the symbol corresponding to the old layout, so either you need to come up with some kind of crutch again, or before switching to another keyboard, press some empty key there. But in general, this option works.

Answer 1

Previously, back in the days of win 98, keyboards were sold with the so-called Multimedia buttons, and such keyboards always came with a driver disk for the correct processing of these buttons. Nobody bothers you now to throw a simple driver, it's not difficult (at least under win xp it was easy 12 years ago, and under Linux even easier), the driver can be tied either to a specific keyboard or to a usb controller.

Answer 2

interceptors are probably late intercepting - it is not possible to determine which keyboard.
I think the way out is either to use an arduino as an intermediary
or to hold down on the second keyboard forever several buttons - modifiers ctrl shift alt win then pressing the button will always be a combination with them.
