AW: AW: Multicast over USB?
Over LAN it works. I bind the socket to all the interfaces. The relevant code
is attached. Bot_config is the client, that wants to join the Multicast group
of the server. As I said, this usually works in a not routed network, like via
WLAN, its just USB that sucks.

Hm. Would you please paste the code somewhere?
Did you bind it to the right interface(s)?

On some interfaces MCast is disabled by default. You can change this by adding a route.
