Description: Maximum time allowed for periodic transfers per microframe (μs) |
|
|
|
Note: |
|
USB 2.0 sets maximum allowed time for periodic transfers per |
|
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 |
|
together. |
|
|
|
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. |
