Hello Thomas, Thanks again for your elaborate answers. Now that I understand that we need a USB Host Adaptor CF IO Card, for connecting USB devices to PDAs. But are these cards supported in Linux? I found refereces to the following devices. http://www.ratocsystems.com/english/products/subpages/cfu1u.html http://www.windowsfordevices.com/news/NS7540317850.html http://www.pagecomputers.com/cgi-bin/page/M0027732.html Can you let me know whether drivers for either of the above are supported in Linux? If not, can you tell me, any other product with the same functionality but supported in Linux?
