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.

The compression is used to achieve high frame rates. With regard to the

algorithm described below, while the SN9C105 and SN9C120 the compression is
