There is a resistor called Rref. Please change it from 650 Ohm to 500 Ohm and try. This would force it to work in full speed.

I have tested this and it does not seem to change anything and all high speed USB traffic is still directed through to the EHCI in the host machine. Any other ideas. I have worked around this issue by disabling the ECHI in the host but this means they have no high speed support now so it quite a compromise but means it works for now.
Please remove Rref and try.
