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