[U-Boot-Users] usbserial.c for 2.4.20-8smp

[KokHow Teh]

Hi;
      With reference to the mail archive
http://sourceforge.net/mailarchive/message.php?msg_id=9819913, I would like
to know where can I donwload usbserial.c for my Redhat 9.0 (2.4.20-8smp)
for my linux host in order to run usb console properly. There is this
reference in the mail PET/src/os/linux/drivers/isb/serial/usbserial.c but I
don't know where does this PET refer to. Any pointer is appreciated.
Thanks.

Regards,
TEH
