Hi All,

I have PCI memory card reader supporting SD/MMC and MS/MS-Pro memory
cards. For SD/MMC memory cards SD host bus driver gets loaded for
enumerating SD/MMC cards.

When i used SD card, Secure Digital Storage Device is loaded. When i
see the driver details from Drivers tab, sffp_sd.sys driver is
installed for the SD Card. When i used MMC card sffp_mmc.sys is
installed. This happens for windows XP x86 with SP3.

However when i did the same in windows XP x64 with SP2, SD was loaded
successfully but MMC card was not detected. When i looked at <ROOT>
\system32\drivers folder sffp_mmc.sys did not exists.

I would like to know if MMC card was supported for Windows XP x64. Is
there any hotfix for enumerating MMC card?

Any help is much appreciated.

Thanks and Regards,
Sushma

I posted the same query to Microsoft. In reply they said, sffp_mmc.sys
is not supported for Windows XP x64.

Thank You.

Sushma
