Thanks for the info. Do you know of a good USB hub that is compatible with Linux? Most of what I've seen require Windows and Mac so I may need to do some hacking to get the driver working. Any recommendations?

if you do not want to make a custom board use the usb signals on the 24-pin
get a usb hub and usb-serial adapters. you'll only need a 3.3v voltage
regulator and 2 capacitors http://gumstix.net/wiki/index.php?title=USB or
just a cap-free voltage regulator (for example tps73133)
http://www.ti.com/lit/gpn/tps73133 (capacitor is recommended but not
connect Vin to V_BATT (5V) and Vout to USBH_PWR1 (3.3V) plus ground. this is
the easy way

Like movies? Here's a limited-time offer: Blockbuster Total Access for one month at no cost.

I don't think you will be able to find a usb hub that doesn't work in
Linux (hmmmm, double negative translation: "they all work in Linux").
They won't say it on the box, but it will still work.

I havn't found a hub that does not work (yet).
I just picked up a 'dynex' hub and 'dynex' usb->serial cable for using with my
gumstix and they both work under linux. The hub is connected to the gumstix
and the converter is running off my workstation to the console serial port. I
got these from my local Best Buy store.
