USB composite device with multiple HID interfaces

leesommerville — Thu, 14 Feb 2019 05:16:09 GMT

Hi,

I am wanting to develop a device that enumerates as a USB composite device with multiple HID interfaces (that use the Vendor defined usage page).

Does the Kinetis SDK support such a device?

If so, can someone please point me in the direction of an example and/or documentation?

If not, are there any alternative libraries that may support this functionality?

Thanks for your time.

Cheers,

Lee

Hi Lee

if you don't find a solution with the SDK you can use the uTasker open source project from GitHub which will give you flexible composite USB that works on any Kinetis part and will allow you to simulate the complete operation.
For professional work you can consider the higher performance supported version.

Hi,

there is keyboard+mouse composite demo in SDK. You can find them in \boards\frdmk22f\usb_examples\usb_device_composite_hid_mouse_hid_keyboard
