  18Description:    Maximum time allowed for periodic transfers per microframe (\xCE\xBCs)
  19
  20                [ USB 2.0 sets maximum allowed time for periodic transfers per
  21                  microframe to be 80%, that is 100 microseconds out of 125
  22                  microseconds (full microframe).
  23
  24                  However there are cases, when 80% max isochronous bandwidth is
  25                  too limiting. For example two video streams could require 110
  26                  microseconds of isochronous bandwidth per microframe to work
  27                  together. ]
  28
  29                Through this setting it is possible to raise the limit so that
  30                the host controller would allow allocating more than 100
  31                microseconds of periodic bandwidth per microframe.
  32
  33                Beware, non-standard modes are usually not thoroughly tested by
  34                hardware designers, and the hardware can malfunction when this
  35                setting differ from default 100.
