You might want to experiment around a little. Try adding some printk() statements at various places throughout the sd_spinup_disk() routine so you can trace the flow of control. The TEST_UNIT_READY and auto-REQUEST_SENSE parts of the usb-storage debugging log correspond to where the routine calls scsi_execute_req() near the start, with cmnd[0] set to TEST_UNIT_READY. You want to reach the part where it calls scsi_execute_req() with cmnd[0] set to START_STOP, about halfway down.
