Google the meaning of GPIO. If your chip lacks enough physical pins, GPIO lets you use the same pin for multiple hardware functions. Of course, this adds latency—something you'll notice when writing your first firmware for an ARM CPU. But let's face it, you're probably not going to get that far.
Zero tolerance for idiots.

Just wanted to bump this with a post, I can’t guarantee this works with every setup, but I can get “FullSpeed” mode on a modern board with no bios changes, basically, on desktop I click the desktop and swirl my mouse, I then press the power button (not hold) on my pc but keep swirling the mouse until the pc is off, turn back on as usual and it puts it into Full Speed mode instead of High Speed (works in USB 3.0 port, my pc doesn’t even have 2.0), it also works on my PCIE usb card, so this makes me think it will work on other setups.

This is obviously a strange bug, but it works.

USB 3.0 can work in USB 2.0 mode.

But the 2.0 USB port isn't connected directly to CPU and any guide I was reading suggests you should plug your mouse to the USB ports which are directly connected to the CPU and not USB controller. Also It's kinda strange that I don't have most of the options you guys have but then I have an AM5 board maybe because of that.

Anyone on an AM5 Board who made some changes and had positive results?

So you did some changes with SCEWIN on an AM5 board? Do you remember which one?

of course i have list,first i import settings in scewin restart pc and do benchmarks and test,if i like it i wrote it down,but with my new asus mb scewin export maybe 10% of the options,i want to at least disable HPET like on my old mb via scewin with a single restart of the pc.
