scc2 conflict with usb?

Hello,

I am able to run a usb slave driver in linux 2.4.7 on 823/850
(rpxlite) boards.
problem being faced is that usb (scc1 addres space) works when my
CPM ENET is not either at SCC1 or SCC2.
when I enable ENET on SCC3 my UART conflicts and says during
compilation
uart.c:68: #error "Can't use SMC1 for console with Ethernet on
SCC3"

guided by this now when i enable console on SMC2 it compliles but
no o/p during booting on screen.

looks like uart.c file need to be looked upon.

ENET on SCC1 would conflict with USB as there would be clash of
interrupts (CPMVEC_SCC1),
But I am not able to understand why ENET on SCC2 disturbs USB at
all.

is there any solution without touching uart.c file ?

Best Regards,

How does USB conflict with SCC2 in Ethernet mode?  The default
configuration should just build this way, since the only thing
you can run on SCC1 is USB.  On an 823, the default (and about
the only configuration) is USB on SCC1, Ethernet on SCC2 and console
on SMC1.  Not all parts have SCC3.

Thanks.
