Yes, you are rigth, but consider that all the interfaces received by
pcap_add_if_win32() can be opened. The reason is that the list of adapters
is obtained in pcap_findalldevs() by means of the PacketGetAdapterNames()
packet.dll function. This function returns only the adapters that it's
actually able to open.
Therefore, the check that you propose should not be necessary, because the
call to pcap_open_live() inside add_or_find_if() will always succeed.
However, does this patch solve your problem?

What do you mean by 'mib'?
