We don't have these cameras on hand to test and debug. Could you  
locate these devices in the output of the command:
     sudo lspci -v

and send the result please ? (not the whole output, just the lines  
referring to these devices)

It is the version of vic which is important - could you check that you  
have the latest version of vic (which fixed Philipppe's problem). More  
specifically, ensure that you have installed:
	ag-vic2.8ucl, version 1.4-0ubuntu6
