| 4 | NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx |
| 5 | driver and thus may have bugs that are not present in the original version. |
| 6 | Please send bug reports and support requests to <luc@saillard.org>. |
| 7 | The decompression routines have been implemented by reverse-engineering the |
| 8 | Nemosoft binary pwcx module. Caveat emptor. |

| 28 | 4 different qualities (no compression, low, medium, high). |
| 29 | It lists the bandwidth requirements for said mode by its alternate interface |
| 30 | number. An alternate of 0 means that the mode is unavailable. |

| 32 | There are 6 * 4 * 4 entries: |

| 34 | 6 framerates: 5, 10, 15, 20, 25, 30 |
| 35 | 4 compression modi: none, low, medium, high |

| 37 | When an uncompressed mode is not available, the next available compressed mode |
| 38 | will be chosen (unless the decompressor is absent). Sometimes there are only |
| 39 | 1 or 2 compressed modes available; in that case entries are duplicated. |
