No: if it works with a hub then it isn't a S/W issue and, if genuinely repeatable, must be a Pico USB host electrical issue when trying to power a keyboard Hm, taht was my first assumption, but I connected 5V (from 5v linear lab bench power supply) to USB. There definitly is enough current and meassured the voltage (spot on 5V)... Whatever... In any case I much prefer the converter method with two picos, this way I can use PS/2 and USB    So this isn't a problem. I was just asking in this thread if, there are any problems I might oversee for my pinout. I don't wanted to start a whole new discussion, there is already a thread for that (link).
