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]

作者: luobing4365 时间: 2005-12-28 16:52

能否把源代码一次性提供下载，边看边分析，这样看太急人了 ^^

作者: luobing4365 时间: 2005-12-28 16:53

满佩服的，再顶一顶

作者: wwwwillis 时间: 2006-3-27 14:03

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。

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

case IOCTL_DISK_GET_DRIVE_GEOMETRY: //0x70000 Include ntdddisk.h

maingao.你好。
我是007blue，以前我们联系过，我刚学完单片机，现在开始做U 盘，选的芯片是AT89C51SND1C,8位，它最大能做多大容量的U盘。能否发点关U盘的资料给我，我的email --zouna214@yahoo.com.cn谢谢
