STM32F105 VCP problem

Question asked by qian.evan on Dec 22, 2012

STM32 experts:

I have a STM32F105 board and was learning the virtual com port with "STM32_USB-Host-Device_Lib_V2.1.0" library. I didn't know why  the VCP_DataRx function was been called one time when PC USB host send data,  but the VCP_DataTx can work ok!

I only changed the config of the USART2 port setting to PA2, PA3,  and LED1, LED2 port,  who can help me!
