Indeed, really good idea. It's an strategic strike - David =)
I guess one needs the latest Aranym version for that?

I really like the idea! But... Is there an USB support for the firebee 
within FreeMiNT for the
FireBee? I guess - no. ( yes, there is support for USB, but it has 
nothing to do with
FreeMiNT or Davids USB driver/module structure ).

If there would be support for accesing the USB chip of the firebee - 
one could just develop the
specific device driver under Aranym, and then load that module under 
FreeMiNT for the firebee...

I believe that's already possible for people who own an NetUSBee or 
Ethernat, - it probably
makes development of USB device driver modules much more comfortable.

However, as there is no USB support within FreeMiNT kernel I can not 
make much use of this
great feature ( except if I would like to develop an driver for 
falcon/NetUSBee ).

I would like to know what's missing for USB support within FreeMiNT for 
Coldfire.
I believe the Chip by itself is already supported by David's work. It 
just the communication
with that chip (which is specific to the platform), which is missing, 
is that correct?

How could that missing stuff be added? How much work is to expect for 
that? I believe it would
be good to stick to the Freescale stuff when developing such an USB 
base system driver, but I
guess the driver infrastructure currently isn't aware of things like 
the DMA API for freescale
family?
