18Description: Maximum time allowed for periodic transfers per microframe s)
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.
