cf card reader writer

I want to design a CF Card Reader/Writer interface USB using PDIUSBD12. I don't know how to write program run in Window 98/2k to detect my circuit and see it as Removeable Disk.

Best regards!
 

Did you consider using a dedicated solution ? (for example the ISD-300LP from Cypress). It will give you the full transfer speed, which is very important. For example, I'm very dissapointed after trying to implement a SmartMedia card writer on USB using the FT245BM device from FTDI, because I can't get enough speed, even though the protocol is working fine.
If you still want to use PDIUSBD12, check this link:

It should give you some pointers.
 

Thanks for your reply, I have found a chip for CF reader, It is C236 of OnSpec, This IC support to CF Card connect to PC using USB interface, it's very easy for user, but I don't have datasheet of it. If anybody have it, please send to me.
thanks
