Solved [Solved]usbus0: That device doesn't support promiscuous mode

Hi all,

I am unable to use tcpdump due to:

Code: 
kim-data# tcpdump -nS
tcpdump: WARNING: usbus0: That device doesn't support promiscuous mode
(BIOCPROMISC: Operation not supported)
tcpdump: WARNING: usbus0: no IPv4 address assigned
tcpdump: packet printing is not supported for link type USB: use -w
kim-data#

Google didn't have much to say. I don't have a clue.

Thank in advance,

Mike

I found the culprit. I had swapped nics while troubleshooting. The new card was configured and worked fine. When I swapped back to the original card tcpdump worked fine again.
 
You can always add the -i option to specifically use a certain network card.
 
Thanks SirDice!

@SirDice,

That helps me understand what was happening. Also, had I reviewed the man page more carefully, I could have possibly solved this myself. Thanks for your many contributions to the FreeBSD Community!
