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!
