d12枚举的问题，（图）

 into SETUP_read ...
 80_06_00_01_00_00_40_00_
 this comming to  USB_submit
12_01_10_01_00_00_00_10_71_04_11_11_01_00_01_02_end of USB_submit
int-n is coming data1 = 0041
if ==1 theis is coming ....
 into SETUP_read ...
 00_05_02_00_00_00_00_00_               =======这里要求地址
 this is setaddress....this comming to  USB_submit   ==给了地址
end of USB_submit
int-n is coming data1 = 0002
this comming to  USB_submit
end of USB_submit
int-n is coming data1 = 0041
if ==1 theis is coming ....
 into SETUP_read ...
 80_06_00_01_00_00_40_00_            ==又来要描述符
 this comming to  USB_submit
12_01_10_01_00_00_00_10_71_04_11_11_01_00_01_02_end of  USB_submit

 00_05_02_00_00_00_00_00_
 this is setaddress....this comming to  USB_submit
end of USB_submit
int-n is coming data1 = 0002
this comming to  USB_submit
end of USB_submit
int-n is coming data1 = 0080
this commandid = D12_suspend
this commandid = 0x80

遇到过同样问题的朋友帮个忙出个主意啦！

你用这个东西捕捉数据看看
应该能够找出问题在什么地方。
枚举过程是：
get_descriptor（device）
set_address
get_descriptor（device）
get_descriptor（configuration）
get_descriptor（configuration）

set_configuration
get_configuration

其余是特定设备的请求
比如HID有
get_protocol
get_descriptor（class）

对数据仔细分析就会得出那个地方出问题了！

多谢，感觉是setaddress之后出来的问题，好像设置了端点地址之后，没有按照新设置的端点发送数据给上位机！

先是是看吧！
