dadoo1,
I have one, but I haven't been able to make it work using the standard Sharp ROM. If yours is the same (orange card with two lights) then it is the new revision B card based on the Agere Systems chipset. I tried building a driver for this from the source code published on the Archos website. The driver would load, but I never got connected. I think the driver is built into some of the alternative ROMs like OpenZaurus - you might have more luck with them.
