For those who might not get it, every laptop that I’ve had has had two usb 3 ports on the right side, with other I/O like HDMI or headphone jack, and then one USB 2 port on the left side with less io, just the power jack.

It’s different because of how the pins are connected. C-to-A uses 4 or 5 pins (with or without id pin) out of 24 in total for USB C. My guess is that it negotiates differently in that scenario. I’m guessing those problematic USB C devices only connect those 4 or 5 pins and don’t properly “talk USB C”.
Ah that'd make sense
