    libpayload: Increase USB EHCI transfer timeout
    
    The EHCI driver defines a maximum transfer timeout of two seconds. The
    comments state that during tests the maximum amount of required transfer
    time was for the SCSI TEST_UNIT_READY command on certain devices. We
    have now observed a USB device (Patriot Memory 13fe:3100) that can NAK
    this command for slightly more than two seconds. It will also completely
    fail if the timeout hits, since it gets confused by the subsequent CSW
    retry/recovery mechanism and starts producing babble errors. This patch
    increases the timeout to three seconds to circumvent this problem.
    
    To test, boot a Falco from a red-black RageXT USB stick.
