PreReset and USB

HI

I am still strugling with my linux booter for RISC OS.
I use SoftLoad as base for my effort and everything works except for USB. SoftLoad uses a call ServiceCall with PreReset. That causes USB to shutdown beyond recovery. I don’t know how to reinit it, tried to do a complete i.mx6 usb init code sequence, but no luck.
The errors I get from linux are power related erros.

However I have played with not disabling interrupts and that makes my keyboard to light up when linux starts ( but fails to work ).

I have been checking the PreReset now , and the only thing I can think of that I want is to shutdown/reset/flush DMA.

Is that possible?

*rmkill DMAManager

That enabled linux to start without PreReset , but still no USB.
