What is on Linux the major and minor number of the device file for the
cam? on FreeBSD it is:

$ ls -l /dev/video0
crw-rw-rw-  1 root  operator    0, 146 19 mar 09:02 /dev/video0

it seems that the algorithm in vidinput_v4l.cxx depends on minor
numbers below 63 in void  V4LNames::ReadDeviceDirectory()

see also the CVS comment:

 * Revision 1.3  2003/11/25 22:55:13  dsandras
 * Added fallback using major and minor numbers for detection of devices
 * when /proc/video doesn't exist
 (some 2.4 kernels and all 2.6 kernels).
