You run SCLK @ 133MHz the SL811 driver won't work at this speed without the
DUMMY_DELAY option enabled!
Adjust the EBIU timings of the bank the SL811 is connected to.
Then set a proper DUMMY_DELAY bank that fits the additional cycles of delay
needed to talk to the SL811.
I'm sure that will fix your problem.

Thanks for help. We slow down the EBIU and the USB work now.
So close this bug now....
