离成功就差一步的问题了，read10响应出错
我是用 USBN9603+ARM7开发的虚拟U盘，在程序中直接返回了U盘的应答数据。
但是在read10的时候老是出问题。程序里面明明传送了CSW，可通过BUS BOUND截获的数据里却没有。然后就直接主机继续read10了，我后来修改了程序，在发送数据的时候disable了接收端口，但问题依然存在。 各位兄弟姐妹帮帮忙，谢谢了 。附bus bund数据 Phase Data Description ----- -------------------------------------------------- ---------------- CTL 80 06 00 01 00 00 12 00 GET DESCRIPTOR LEN 12 00 00 00 18 DI 12 01 10 01 00 00 00 08 1a 14 31 01 00 00 00 00 ..........1..... 00 01 ..
