This question is an exact duplicate of:
As the title states I want to connect a USB mouse to the USB port on a USB/UART bridge. I want to determine if it is possible to communicate with the mouse using serial commands on the FPGA board then converted to USB signals.
In other words, I want the bridge to serve as the host to a peripheral like a mouse/keyboard. Do I need to worry about converting to PS/2 at all when connected?
Is this feasible as I am looking for a viable solution to connect a mouse to my FPGA board without having to create a USB block to handle this from scratch?
