But you still don't need USB particularly.

For Android emulation you'll need 3D acceleration to get good
performance anyway, which upstream QEMU doesn't have.

This should work, so yes, if it doesn't you'll need to debug why not.
I have no particular advice on where to start, I'm afraid, because
keyboard and mouse input have always just worked for me.
