Using touch screen with v90le

I am trying to use a elo touchscreen with my v90le thin clients. I have the sld file (driver) required but I have never added a driver to a embedded xp install before. From what I have read I need to add the component to the xpe image using MS Component Designer and then use Wyse's WDM to put a new image on the thin client. Am I far off?

I don't mind reading a figuring it out but there is a lot of information out there doing it different ways. Does Wyse provide there XPe image. I have downloaded the latest XPe package for my version of thin client.

If someone could point me to a URL that provides Wyse's instructions on how to add a driver to their system I would really appreciate since I have not found one yet.

Thanks in advance,
Jason
