finding USB camera using kdf and lsmod, etc

[Steve]

You need to add the path to programs to your PATH environment variable 
otherwise the shell cannot find the programs you tell it to run.

Typing su by itself says "become root, but retain all my useer 
environment" - which is fine but doesnt load roots PATH environment.

using 'su -' gets around that, the - says "change to root and load all of 
roots environment as if I had logged in as that user"

Windows has exactly the same issues with PATH environments - it just hides 
it really well by defaulting to let the useer run anything.

'man su' describes some of this - but to fix your immediate issue, try 
adding a '-' to the end of the su command.

The reason you cant run programs when in the /sbin directory is also 
related by the way, as '.' (the current directory) is also not in your 
PATH (which is done on purpose by the way..) - it is there by default in 
windows.

You can change this behaviour by editing /etc/profile and removing the 'if 
UID = 0 then do the pathmunge stuff' statement and just having the 
pathmunge stuff by itself (including the . directory if you are 
exceptionally brave)
