Yes, I have the same impression about the errors. We need to test
again in detail all speed modes to get a better overview, but the system
works fine. If there is a higher layer protocol that supports flow
control then this bit error rate is practically nothing.

Hi,
We tested the code on our board. Now the USB host controller
functionality works almost perfect, with some losses at very high rates
(921600), while it does not crash any more nor with use-to-serial USB or
other media devices.
Thanks a lot,

Good to hear, I spent a couple of days tracing the behaviour, and was
happy to find it to be a one line fix. That in-appropriate
halt_channel() call was causing cross-connecting references as I recall.
I also still see some errors, but it seems to recover from them. I
assumed they are due to random glitches/errors on the hardware lines.
