am335x usb1 host wince7, before the wince7 system booting up with inserting the u disk , the wince7 system can't identify .but if after the wince7 system boot up, then insert the udisk , it is normal . for solving this problem ,we debug the information ,as follow:

I think,the importance error information above,just
m_portBase->DEVCTL = 99

please help me to solve this problem
above,it is normal ,don't go wrong
this circuit go wrong
