Electronic – arduino – Can simple microcontrollers read signals from a USB to RS232 converter connected to a USB mouse

arduinohidserialusb

Trying to connect as many usb mice to my arduino and just got informed of usb to rs232 converters.

Can anyone tell me if it is possible to simply connect a usb mouse to a usb to rs232 converter, connect some wires from the rs232 output plug to the microcontroller and then read the data for all mouse events?

Best Answer

No, but you could plug the mouse into a USB to PS/2 converter which will make the mouse switch into synchronous serial mode. You would need a matching mini-DIN socket fed with 5V but decoding the data should be fairly straightforward. See here for the wiring.

USB to PS2 converter

UPDATE

I just tried this with a couple of new mice and they worked OK. As an afterthought - remembering that PS/2 mice work in asynchronous mode with a PS/2 to DA9 adapter - I tried cascading USB => PS2 => Serial adapters (with external power grafted-in). Needless to say, USB mice don't support legacy async serial mode (well it was worth a shot!).
