   NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx
   driver and thus may have bugs that are not present in the original version.
   Please send bug reports and support requests to <[email protected]>.
   The decompression routines have been implemented by reverse-engineering the
   Nemosoft binary pwcx module. Caveat emptor.

/* This tables contains entries for the 675/680/690 (Timon) camera, with
   4 different qualities (no compression, low, medium, high).
   It lists the bandwidth requirements for said mode by its alternate interface
   number. An alternate of 0 means that the mode is unavailable.

   There are 6 * 4 * 4 entries:
     6 different resolutions subqcif, qsif, qcif, sif, cif, vga
     6 framerates: 5, 10, 15, 20, 25, 30
     4 compression modi: none, low, medium, high

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