Hi! I'm having some fun with usb host. Good news is it works with externally powered hub... after a while. I get some error messages about inability to go host mode, but with enough patience it eventually does enter host mode and I see my keyboard/mouse. And usually in that process, one of my cpu cores disappear. top no longer shows 2 cores, and I was wondering for a while if d4 is single-core system. It is not, my two cores are back after reboot. That's with 6.1.9 kernel from leste. Ideas how to debug this would be welcome. (Do you use usb host?) Best regards, Pavel --
