Custom driver required for combined USB keyboard / mouse device?

NTDEV

Hi,

I am writing firmware for a USB device that has both a keyboard and mouse
interface.
Both interfaces send data on the same USB endpoint, using seperate usage
pages
in the report descriptor.

The device works fine on a Mac, but Windows has problems enumerating it.
It appears with Code 10 in Device Manager, and does not work.

Is there a class driver in Windows (from XP onwards) that supports such a
device,
or is a custom driver needed?

If anybody has good examples of working descriptors too, that would be
appreciated.

Thanks,

Daire

This is one Device and two Interfaces (one keyboard and one mouse)? This is classic case for a Composite USB Device, which will then be claimed by Windows Common Class Generic Parent driver, resulting in each Interface appearing to be a separate device in the system, so they can be claimed by the typical Windows drivers.

as well as the material surrounding this page.

Actually in this case, the muxing happens at the hid level. No need for the genetic parent. The code 10 means the hid USB class driver didn’t like something about your descriptors, I would guess specifically your hid descriptor
