usb device Linux support

Is there Mini2440 Linux support USB device(slave)?
I'm interested in implementation of Virtual Com (CDC) class USB device on
Mini2440.
Did anybody have experience in Virtual Com on Mini2440?

Hi,

I haven't tried this yet, but try to look up usb gadget for linux.  I found
some of the kernel modules in the DVD.

to Gerald
What are kind of those modules?
Are those kernel modules reliable,tested?
May be me to look to WinCE side?

I found some of the usb drivers in 

\Micro2440\Samsun S3C2440
Sources\firmware_BSP\s3c2440_kernel2.4.20_cee31_rel1.0.tar.bz2

There are some drivers relating to usb devices in the .tar.bz2 file in the
directory: drivers/usb/device

I'm still new to linux, so I'm not entirely sure how to rebuild and run the
kernel modules.  If you get anywhere with these modules, please let me know
of any progress.
