We checked what you mentioned but found that the PHY reset is identical
between XM and C4. The reset signal is ok. That is what we saw on an
oscilloscope.
We also found that the USB2HS_CLK initialization does not work, also
with the oscilloscope. I am going to check the CLK initialization
sequence in beagle.c/ehci_hcd_init.
