I assume you are talking about legacy devices? I haven't purchased a keyboard in the past ten years with USB-A. Everything is USB-C for charging/data and Bluetooth.
Wow. A device in 2025 with a non-detachable USB-A cable? That sounds like a horrible design decision from both a repairability and future-proofing standpoint. My keyboard has a USB-C port on the side so you can plug in whatever cable you want, A or C, long, short, curled, braided. It even connects to my phone without dongles.
