I'm working with the STM3210E demo board and trying to modify the USB Mass Storage demo function to access only the microSD memory and not the NVRam memory too.  I've removed reference to the NVRam such as initialization but when I connect up a USB cable its still coming up with two devices, two drive letters.  Can anybody point me to the area in that demo firmware that would need modification to tell the USB there is only one drive?

Max_Lun (usb_prop.c)?

And other LUN references throughout the SCSI implementation represent opportunities to indicate there isn't a second logical unit.
