在UsbStorage驱动开发(二)文章结尾处有说处理IRP＿MJ＿DEVICE＿CONTROL中的IOCTL_STORAGE_QUERY_PROPERTY,IOCTL_SCSI_PASS_THROUGH,IOCTL_SCSI_PASS_THROUGH_DIRECT,请问怎么处理，谢谢！！[em02]

请帮我分析IOCTL_STORAGE_QUERY_PROPERTY,IOCTL_SCSI_PASS_THROUGH,IOCTL_SCSI_PASS_THROUGH_DIRECT，还有IRP＿MJ＿DEVICE＿CONTROL要处理哪些。

请问处理IOCTL_STORAGE_QUERY_PROPERTY是否有问题？

请帮我分析要不要处理IOCTL_DISK_GET_DRIVE_GEOMETRY，分析其正确性。thanks
