     Hi, I have a device that looks like this one on eBay...

http://cgi.ebay.com.au/USB-2-0-Cable-DB9-pin-RS232-Port-Serial-Adapter-/270617246434?pt=AU_Laptop_Accessories

     I'm not sure this is exactly the same as what I have (internally) 
but its the same molded body as what I have, this is running on my Linux 
box that allows me to monitor the Tevion UPS that is serial only.

     I'm running the following modules, pl2303 & usbserial..  lsusb 
gives this device

Bus 005 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial 
Port

     And for the money, much better than a new mobo, or sourcing another 
mobo who has a serial device :)
