    USB: Dealias -110 code (more complete) · 38e2bfc9
    Pete Zaitcev authored
    The purpose of this patch is to split off the case when a device does
    not reply on the lower level (which is reported by HC hardware), and
    a case when the device accepted the request, but does not reply at
    upper level. This redefinition allows to diagnose issues easier,
    without asking the user if the -110 happened "immediately".
    The usbmon splits such cases already thanks to its timestamp, but
    it's not always available.
    I adjusted all drivers which I found affected (by searching for "urb").
    Out of tree drivers may suffer a little bit, but I do not expect much
    breakage. At worst they may print a few messages.
