大家好，我初次接触USB，用的是ATmel公司的AT90USB162单片机作为USB设备，希望将设备配置成鼠标，这样可以避免驱动的编写，但是在枚举过程出现问题，以下是用Bus Hound抓取到的设备插入USB接口后的枚举过程：
Bus Hound 6.01 capture on Windows XP Service Pack 3 (x86). Complements of www.perisoft.net
Device - Device ID (followed by the endpoint for USB devices)
(18) JTAGICE mkII

Phase - Phase Type
CTL USB control transfer
IN Data in transfer
USTS USB status
Data - Hex dump of the data transferred
Descr - Description of the phase
Cmd... - Position in the captured data

我又特意用一个USB鼠标作为对比，以下是鼠标的枚举数据：

我比较了两者的数据，发现自己的设备在进行到USTS c0000004 stall pid 这个步骤就停止了，很奇怪不知道怎么回事？也不清楚USTS c0000004 stall pid是什么意思？请哪位高手指点一下，告诉我是哪里的问题？应该如何修改我的固件程序？谢谢了！ |
