Yes, USB flash drive and PS4 controller connected to USB hub. Everything is working as expected, VMU recognized in games, OLED working. Very strange, only buzzer is not working.

maybe your buzzer is active and designed for higher voltage or your buzzer is active and you mixed up the polarity.
I use a passive buzzer taken from an old pci dialup modem

There is a "+" marking on both buzzers to which I have paid attention, but at one point have intentionally reversed polarity on one buzzer to see what will happen. Obviously, same result, not working, lol.
I will most likely have to buy a few from aliexpress. Since yours is working, can you measure resistance on your buzzer? There are many listings on ali with different resistances.

Tada! Unfortunately my buzzer stopped working, but it's mostly done!
Fantastic build! Pretty much my dream implementation, tbh. If it were me I'd go for dual USB A ports but that's not a criticism, just taste. And it probably wouldn't be as clean as what you've ended up with.

I seem to have an issue... suddenly my USB4Maple adapter is not following the VMU2 function of where it has a different VMU bin file for each game in GDEMU. I don't know when this issue started happening. But just a few days ago, it would load a new bin for each game. Now it only loads the default bin.

You're right... I forgot I went back to an older version, because the most recent version makes it so that I can't boot without a VMU.

I think I would want to sell these, but the cost of many of the internal parts make it pretty impossible to put up a good price.
