Raspberry PI zero USB - problem

[Wojciech Puchar]

i have raspberry Pi ZERO - power over USB and USB on the go, serial 
console
everything works except USB. When i attach pendrive to it over USB nothing 
happens. While at boot usb is detected, even uhub so everything should 
work.

In the same time pendrive is detected when i try to boot with it inserted.


what am i doing wrong. RPi Zero is descriped clearly here:

https://wiki.freebsd.org/arm/Raspberry%20Pi

and USB works both device and host.

is there something that must be set to make it work under FreeBSD?
