Hi Everyone.

I am working in stm32f103xx  .

it has usb 2.0 full speed.

 now i need to  enumerate usb as virutal com port . i downloaded usb example from st.

i changed in platform config according to my evaluation stm32f10b . then in hw_config i edit the usb disconnect pin as pb4. pin pb4 is jtag as default then i remapped as gpio..

     GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable, ENABLE);.

then i compiled and load into my board. but nothing happen while connecting into my laptop using windows 7.. 

there is nothing to change in the example.
