When keyboard has multiple boot keyboard interfaces only the first one is handled but others is ignored.

Rapoo 9300M doesn't work with USB-USB converter. It has two boot keyboard interfaces and the second one is what we need to handle.

Rapoo 9300M USB descriptor:

Keyboard at interface 1 sends vendor specific data, system/consumer control.
Keyboard at interface 2 sends normal keyboard data.
