I have a Startech US2GA30 with the chipset Realtek - RTL8156 that works for normal functions and appears as UE0, however I want to use it in promiscuous mode for running Snort. When I set it for promisc in ifconfig is says it is in promisc, however I only see arp and broadcast traffic which tells me it isn't actually in promiscuous. The manufacturer states that the chipset supports promiscuous, so I suspect this is in the driver. Any helpful tips for getting it to work would be appreciated.
