已加载符号文件usbport.pdb。

kd> lm m usbport start             end                 module name
fffff880`03da2000 fffff880`03df8000   USBPORT    (pdb symbols)        
c:\symbols\microsoft\usbport.pdb\71BCD350024D47208D5EA216690A7BFF1\usbport.pdb

所以这是＆＃34; 公共操作系统符号＆＃34;它不包含所需的数据类型＆＃34; usbport！_USBPORT_MINIPORT_DRIVER＆＃34;。

它适用于Windows 8吗？我目前正在调试Windows 7 VM。实验证明是的，它适用于Windows 8。
