Hi Brad,
 
Thanks for your information. But what kernel modules do I need?  Do I need a usb gender switcher and/or the 24-pin flex connector to do this? See the links I found:

usb gender changer.

What is the 24-pin flex connector?
How do I get a gumstix to talk through a USB wifi dongle to a wireless
network?
What must be done to load a USB memory stick?

Thanks a lot!
Mary

This is probably a sign that you need some kernel modules added for
the various usb adapters. If the kernel module isn't on the gumstix
then it won't create the tty device.

Some of these kernel modules are available as packages to ipkg. I'm
not sure how to handle the others... maybe ask here specifically how
the modules you need can be packaged.
