The QEMU USB mouse claims to support the "boot" protocol (bInterfaceSubClass is 1). However, the mouse rejects the Set_Protocol command.
The qemu mouse does support the "boot" protocol specification, so a simple fix is to just enable the Set_Portocol request.
Isn't it true for the USB_TABLET as well?
The USB tablet appears to also advertise that it supports the "boot" protocol. However, its reports aren't "boot" protocol compatible. So, it really shouldn't claim that. A fix (briefly tested) is below.
