I have two slave USB devices, one microcontroller and one real-time target machine (the latter is interfaced with a USB to RS232 cable). I would like to send serial data from the microcontroller to the target machine.

Is it possible to use a RPi as host for both and pass through the input of one USB port to the second port on the Rpi?
