Playing devil's advocate, it can be a major problem if these USB-C to USB-A adapters can't be found anywhere. Around here, I've looked at several physical stores, and nowhere seems to sell an adapter from USB-C plug to USB-A socket. Or even a straight USB-C to USB-C cable; what these stores call "USB-C cable" is always an USB-A plug to USB-C plug cable.

Amazon has dozens of different models. If the physical stores don't have it, that is an indicator that they are low-volume items, i.e., only few users have this problem at all.

Alibaba is selling them for very cheap. I both a few for few dollars and then shipping itself is very cheap.
