Re: How to acquire the driver information from wince420 ?


Hi:

I just use a standard SD controller chip ,two 256MB flash chips and that
sort of things. The host machine is a PDA, in this circumstance , how could
I acquire the port address of the SD interface? I have tried to use
RegOpenKeyEx and RegQueryValueEx to obtain the Handle and ClientInfo of the
active SD card. Can I get more information of it ? Especially , the Port
Address.

Btw, do you mean I can't use Enum api function to acquire the information of
SD card ?
