ResetATA和GetMaxLUN和处理处
我用D12开发的MASS STORAGE，开发卡在了ResetATA和GetMaxLUN和处理处，希望那位兄弟指点：1。我觉得有问题的地方做了注释，望各位帮我看看。
2，我已经跟踪过，发现ResetATA和GetMaxLUN没执行啊，为什么？望那位兄弟指点 不好意思，没法编辑BOUNDHUB的数据啊： CTL 80 06 00 02 00 00 2e 00 GET DESCRIPTOR DI 09 02 2e 00 01 01 00 a0 //描述符集应该是正确的我已经检查过了 32 09 04 00 00 04 08 06 50 00 07 05 80 00 10 00 0a 07 05 00 00 10 00 0a ........ 07 05 81 03 10 00 0a 07 05 01 03 10 00 0a ......
