+/* 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.
