Are you sure that's how your device's endpoints are laid out? Many USB
mass storage devices only have bulk pipes.

How did you install this? What was the device ID you put in the INF,
exactly? Hint -- if you used a USBSTOR\xxxx device ID, then you are
loading at the wrong spot in the stack. You would need to be a storage
device, not a USB device.

Even if you did load on the USB\VID_xxxx&PID_xxxx device, which is what you
seem to be expecting, I don't think you appreciate what's you're up
against. You can't just pass the read requests through as you receive
them. You have to convert the disk-oriented read requests you get into the
SCSI command set that USB Mass Storage Class uses.
