Unfortunately it's even worse, if I read the chip errata[1] correctly: "i859: SATA 6-Gbps to 3-Gbps Negotiation Can Fail". Which means you can run in trouble, when you try to use 6Gpbs devices on your Pyras eSATA port. However I don't expect many use cases are touched by this.

I was actually excited to use this port
While USB doesn't officially support >2A, it's easy to get even 3A power supplies. And I agree, 2A already seems a lot and I, too, hope idle draw is much lower. There was a video by Trashy a while ago about the energy draw of the devboard (the display will probably use a lot of power, too), though that's of course still with a beta version of the OS that wasn't yet optimised for low idle power draw. And here's an older video if you need it.Uh, why would >2A be required? USB spec doesn't even allow >2A... you need USB-C for that, and Pyra doesn't have USB-C. But more importantly, I would hope idle power draw is well under even 500mA so a normal USB port can charge i
