Description: Maximum time allowed for periodic transfers per microframe (μs)

2020-10-30 08:40:50 +01:00
|
|
|
Note:
|
|
|
|
|
USB 2.0 sets maximum allowed time for periodic transfers per
|
2011-07-03 20:36:57 +04:00
|
|
|
microframe to be 80%, that is 100 microseconds out of 125
|
|
|
|
|
microseconds (full microframe).
|
|
|
|
|
|
|
|
|
|
However there are cases, when 80% max isochronous bandwidth is
|
|
|
|
|
too limiting. For example two video streams could require 110
|
|
|
|
|
microseconds of isochronous bandwidth per microframe to work
|
2020-11-10 15:40:33 +01:00
|
|
|
together.
|
2011-07-03 20:36:57 +04:00
|
|
|
|
|
|
|
|
Through this setting it is possible to raise the limit so that
|
|
|
|
|
the host controller would allow allocating more than 100
|
|
|
|
|
microseconds of periodic bandwidth per microframe.
|
|
|
|
|
|
|
|
|
|
Beware, non-standard modes are usually not thoroughly tested by
|
|
|
|
|
hardware designers, and the hardware can malfunction when this
|
|
|
|
|
setting differ from default 100.
