I found a case where a certain program can send some data via USB-C port but not via USB-A.
The author tested this and it works, but I am not clear on how he powered the Pi 4 and 5 he tested.
I will ask more question.
Meanwhile, I am curious if I could plug in the Pi 4 directly into the USB-C port on my Windows laptop and power it that way? Even if this works, it is not ideal since if I have to go to a meeting and take the laptop with me, I would need to unplug the Pi first.
I can also try to power the Pi from a USB-C dock and leave it at my desk when I go to a meeting.
Or I could try to power it via Power Over ethernet, although I do not have experience with that and I think I need more hardware (PoE hat) for that.
Anyway, comments on whether I could plug the Pi 4 into a USB-C port on my laptop? The Pi 4 is an early version that didn't work with all power supplies, only with their official power supply. I hear they fixed that in later revisions, but I do not have one of those.
Thanks for your comments.
