USB disconnect issue is usually power related.
That may be true, but there are plenty of us running into disconnects that aren’t power related. From what he’s said, I’m pretty sure Edilson is just fighting the disconnects that Libre has known about for months, and which have nothing to do with USB power.
April 17th: La Frite does not have a USB hub so it’s not affected by the timeout issues experienced by the hub. We are in the middle of fixing those issues for Sweet Potato and other boards. And if La Frite meets your needs, that proves to be the case. Sadly, I thought I’d hedge my bet on how much hardware I needed and got a Sweet Potato first. 
May 2nd: We plan to fix this by the time we roll out Linux 6.6 soon. To paraphrase the late Bob Newhart, “What is soon, Mr. librecomputer?”
Anyway, I pulled the AML boards off the shelf again, and verified that no, none of the handful of USB boot devices I’ve been working with have any trouble booting with Sweet Potato (using the OTG port) or La Frite. But even the little 8GB, USB2 thumb drive fails to boot if it’s on one of the hub ports. The console log goes something like this:
[ 33.582312] usbcore: registered new device driver onboard-usb-hub
[ 33.584906] meson-ir c8100580.ir: receiver initialized
[ 33.588738] usb 1-1.1: USB disconnect, device number 3
I don’t have a console log for that same thumb drive in the OTG, because it’s unnecessary: it just boots.
