Title: 16-bit HID Mouse Data
Post by: meglamon on July 19, 2010, 02:21:17 pm

Looking at new USB project. Will the standard HID mouse ( on windows systems) driver accept 16 bit x,y,z position data? Assuming the USB target descriptors are properly setup. I haven't been able to find any examples.

Yes, that works right away. Just make sure to support Boot protocol as well, otherwise you may end up with situations during start up where you can not control the system. But when the real mouse driver kicks in it will switch to Report protocol and you can start sending 16 bit data.
