You've got quite a bit of difference than just console on PSC3.  USB
is on the Ethernet pin group instead of on the USB pin group.  Does
the kernel change the value of port_config when it boots, or does it
leave the value setup by U-Boot intact?

Not over a quick exchange via email.  Your kernel is too old and USB
debugging can be complex.  I'd need to be working with your hardware
to figure out what is going on.
