10 months ago "USB 3 Host port 2" description looks okay, but "USB 3 Host ports 0 and 1" are actually dual-role: Type-C and on most RK3588 boards also a Type-A port. OPi 5+ has a hub connected to one of them, so it's the only supported board so far with two fully working USB 3 ports.
Since dual-role functionality doesn't work and I've seen issues with a few devices (especially connected to Type-C), it would be better for it to remain "Partially working" with the original description + the clarifications above.
Text in main has "USB 3 Host" as "Working", and "USB 3 Dual Role" on a separate line "Partially working". This PR doesn't change that.
And this change has a note "while RK3588s devices have only 1 'full' USB3 port".
So I'm not sure what you're suggesting. Maybe move the "USB 3 Dual Role" line up above the "USB Host port 2"?
PCIe doesn't work with all devices that have drivers: some expect a cache coherent bus, others require MSI (Qualcomm Wi-Fi cards), XHCI wants a root port. We could add a list below with the known working devices.
Good point. I'll fix that.
