I see that Socket have released drivers for an updated CF card here
http://www.socketcom.com/support/sup...an.asp?Type=CF
I just tried to use the new driver for the new card with my older card and it didn't work (or at least I couldn't get it to work)
What I did notice was that the new card seems to come with a decent configuration utility that lets you power the card off without having to eject it.
If anyone finds a way of using the new utility wioth the older Socket CF Low Power Wi Fi card please share the information.
