Not exactly. The USB controller is a USB controller. It is
mapped into the address space of one SCC, and may use some of that
peripheral hardware, but it is not configurable as a SCC.
Since you have the 823e, yes SCC3 can be used.

I believe all the "character recognition" does is either map characters
or terminate buffer operations. If the device is still used as a uart,
just modify the driver to initialize the characters you want (as it
stores defaults right now). You can be a little more fancy and add an
ioctl() if you want. If you want a custom driver that isn't a uart,
then you have to write a new driver.
