hi,
Interface the S12 with an external USB chip.
look the picture

Regards,
Gilles
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC9S12UF32&no
deId=0162468636K100 The MC9S12UF32 microcontroller unit (MCU) is a 16-bit
device composed of
standard on-chip peripherals including a 16-bit
central processing unit
(HCS12 CPU), 32K bytes of Flash EEPROM, and 3.5K bytes
of RAM. In addition
to the in-chip full-speed USB 2.0 interface, the
MC9S12UF32 has built-in
the following interfaces and host controllers: ATA-5
interface, compact
Flash, secure digital / multimedia, smartmedia, and
memory stick. Together
with the flexible I/O ports, 8-channel, 16-bit timer,
this MCU is well
suited for applications such as multi-card readers,
USB thumb drives, and
USB to external harddisk drives. Available in 100-pin
LQFP package. 64-pin
LQFP planned for Q3 2004

I haven't built exactly what you are after but I have exposure to embedded
usb device drivers and they are not small bits of code. If you've read
the requisite USB books you will understand the non-trivial nature of
writing a driver for a usb controller as well as the pain of
certification. I think it unlikely that anyone will give you such code at
this point in time since USB isn't commonplace for low cost designs. If I
am wrong and someone wants to volunteer such code I would definitely be
interested it trying it out myself.

The RS232->USB chip is a good recommendation if you need something quick.
3M baud sounds impressive but how will your 9s12 sci get that kind of
performance? This sol'n requires minimal driver dev.
The parallel version sounds decent (1MByte/sec) but it looks like FTDI
wants to control the device side of the driver. Probably CE and linux
drivers are avail on request. Porting wouldn't be too difficult. The
advantage resides mostly in the chips handling of enumeration and usb
protocols. Disadvantages (from what little I have gleaned from the FTDI
site) are you don't choose the transfer type and you don't get anywhere
the possible 12MByte/sec with USB 1.1 in bulk transfer mode. True usb
control is only possible with a general usb controller chip like the ones
Cypress and National Semiconductor sell.
I'm not familiar with the USB 9s12 derivative - it may make most sense.

The biggest disadvantage of the FTDI chips may be that you can't
direct your data to more than one "end point" buffer which makes you
work a little harder to sort out commands from data. Even so, I have
done USB both ways, and it is a LOT easier to get a USB peripheral
going with the FTDI chips than with more traditional approaches.
Another important issue is that the host side drivers are absolutely
reliable which takes a major load out of your development cycle.
My FTDI/MC9S12 designs easily support 300 kilobytes / sec, which is
faster than most applications require except for disc drives and the
like. The trick with the parallel version is to set up an interrupt
for incoming data, but then switch off the interrupt after the first
character, start a timer, and then don't read the buffer until a few
10's or 100's of microseconds later when the current packet has fully
arrived. Then just transfer all the data that's in the buffer, then
re-enable the interrupt. The usefullness of this technique depends
on how your data is structured, but for maximum throughput take
advantage of the FTDI's buffer and don't get bogged down in an
interrupt per character if you don't have to. This keeps lots
of "interrupt time" available for other peripherals like the SCI's
etc.
