Did you try the driver above?
I think you need to find PRISM 2.5 driver, and install it.
I don't have a Windows CE 2.0 device, but back in the day I remember typing some driver information
(prismnds.dll I think
) in the dialog menu that pops up on a Windows CE 2.11 device.
There should be others who are able to help you out more.
Linksys WPC11 v2.5 driver is reported to work with MA401 too.
Meanwhile, search for "PRISM 2.5 Windows CE 2.0 driver" as there are quite a few posts here in the forum.
