CE loaded hardware list

I have a an SDIO device that is recognized differently depending on the

I am working on the CE driver, but I was looking to see what XP thought
of the hardware. On one system, the device (802.11 device) is
registered as an MMC disk. On the second system, it is an unrecognized
hardware with the correct HWID and VENDID.

On CE, I have the registry key for the SD card as:
HKLM\Drivers\SDCARD\ClientDrivers\Custom\MANF… (with the correct IDs
and func1)
but the driver is not called.

So now I am trying to determine how the hardware is recognized (like the
first XP system or the 2nd)

How can I see what CE thinks this device is?
