An Engineer's Guide to USB Typе-С (2024)

I use an Apple Silicon Mac and often use programmable keyboards like the Royal Kludge RK61 via USB C. when I press keys such as A, S, D, F, W, or nearby keys in quick succession, the keyboard stops responding completely until I unplug and reconnect it. I've even replaced the USB C cable with a new store bought cable, but the issue still persists.

there is a timestamp as parameter, I don't know, what it is good for, but the link works without it as well

Might be for cache busting.

could be, but for pdf documents I would assume that they are not changing this much

Usb isn't the issue, you bought an extremely budget mechanical keyboard.

Pretty good summary. It can be confusing since type C is "just a connector" but it's pretty heavily coupled with the protocol now.
