I am using STM32F373VC microcontroller. I want to interface a usb keyboard to toggle led connected on pin by pressing key on keyboard.please help me.

Do you have a question? Where is your code? Where are you struggling?

USB is asymmetric, you have master (Host) and slaves (Devices). Keyboard is a Device. So you'd need the STM32 to act as Host, but the USB in STM32F3xx is Device only.

So you can't.

But you can connect a PS/2 keyboard to gpio pins of STM32. We did this. Works great.
