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