Then add a routine to your pcap-xxx.c that, similarly to

I didso but when compiled after having add the pcap_platform_finddevs() to
pcap-win32.c I get this compilation error,

Error    32    error C2065: 'any_descr' : undeclared identifier
d:\winpcap\winpcap\wpcap\libpcap\pcap-win32.c    883

This is because of the following part in the pcap_platform_finddevs(),
any_descr

int
pcap_platform_finddevs(pcap_if_t **alldevsp, char *errbuf)
{
    if (pcap_add_if(alldevsp, "any", 0, any_descr, errbuf) < 0)
        return (-1);

#ifdef HAVE_USB
    if (muwis_platform_finddevs(alldevsp, errbuf) < 0)
        return (-1);
#endif /* HAVE_USB */

    return (0);
}

I copied this function from pcap-linux.c and removed the definitions for dag
and
septel cards.

my device name is muwis.

Next I removed the following part from the above code, and the build
succeeded.
if (pcap_add_if(alldevsp, "any", 0, any_descr, errbuf) < 0)
        return (-1);

Is this process acceptable of me removing the above part?
