20 | Note: |
| 21 | USB 2.0 sets maximum allowed time for periodic transfers per | |
| cc62a7eb KS |
22 | microframe to be 80%, that is 100 microseconds out of 125 |
| 23 | microseconds (full microframe). | |
| 24 | ||
| 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 | |
| 4ec0b092 | 28 | together. |
| cc62a7eb KS |
29 | |
| 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. | |
| 33 | ||
| 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. | |

| 72 | or may not need it at all. | |
