本人现有两个不同型号的USB蓝牙适配器,分别将其插入PXA270的实验箱上,系统是WinCE 5.0的,一个正常,另一个不正常
下载一个debug版的WinCE镜像,分别将两个USB蓝牙适配器插入实验箱USB时时串口打印的信息如下:

可以看出,正常的那个USB插入实验箱时能够枚举成功,然后主机打开通信管道pipe
不正常的那个蓝牙插入时枚举不能成功,在DEVICE_CONFIG_STATUS_SCHEDULING_GET_DEVICE_DESCRIPTOR_TEST 和
DEVICE_CONFIG_STATUS_SCHEDULING_GET_CONFIG_DESCRIPTOR (失败了两次)
时不成功

请问是什么原因呢?

另:这个在PXA270上不正常的蓝牙适配器在三星2410的实验箱上是正常的
PXA270和2410的WinCE系统组件是一样的

盼高手指教!
