Level 3 is useful for testing only, when only one device
is used. It also shows some more informations about the
hardware being detected. This parameter can be changed at
runtime thanks to the /sys filesystem interface.

formats over the USB: either native "Sequential RGB Bayer" or compressed.
The compression is used to achieve high frame rates. With regard to the
SN9C101, SN9C102 and SN9C103, the compression is based on the Huffman encoding
algorithm described below, while the SN9C105 and SN9C120 the compression is
based on the JPEG standard.
