So the state machine is blocked
I sent the SUBMITURB and I exect for an async completation here. WHat is the correct behavior of the devio usb when the device does'nt answer to an IN data trasaction. If I fix with a timeout
and set an ISTALL error the emulation go ahead. Is this correct?

Any hints?
