| 2288 | * async: Yes the device uses its own clock but |

| 2290 | * for the host to adjust next packet size |
| 2291 | * |
| 2292 | * sync: - data rate is constant, and device |
| 2293 | * is clocked to the usb bus. |
| 2294 | * |
| 2295 | * adapt: - the device adapts to data rate of the |
| 2296 | * host. If fixed packet size is used, |
| 2297 | * data rate is equivalent to the usb clock |
| 2298 | * so this mode is the same as the |

| 2306 | * async: - the device uses its own clock and |

| 2308 | * |
| 2309 | * sync: - the device uses usb clock rate |
| 2310 | * |
| 2311 | * adapt: Yes the device uses host's feedback (on |
| 2312 | * on a dedicated (output) sync endpoint |
| 2313 | * to adapt to software's desired rate |
| 2314 | * |
| 2315 | * |
| 2316 | * For usb1.1 ival is cardcoded to 1 for isochronous |
| 2317 | * transfers, which means one transfer every ms. I.e one |
