Did you restart the WinPcap NPF driver after you inserted the USB stick? If no, please try this:

  • Insert the USB stick
  • Start a DOS box as administrator
  • run: sc stop npf
  • run: sc start npf
  • check if the interface is now listed: dumpcap -D -M

Regards
Kurt

3G USB modem ... windows7

WinPcap doesn't support PPP interfaces on Windows 7, and mobile phone network "modems" run PPP over the modem phone connection, and Wireshark uses WinPcap for packet capture, so those devices are not supported in Wireshark on Windows Vista, 7, and 8.

Just a comment Guy, lose the scare quotes. :)

There's nothing inaccurate about the term "modem" here, as they literally are performing QAM modulation/demodulation. Also it's not a "phone connection". HSPA data service does not touch a telephone switch, rather the line of path is from the device to the radio network to a GPRS Core (SGSN/GGSN nodes, effectively IP routers for the purpose of user IP packets) to an ISP. In older architectures it wasn't quite the case and carrier telephone switches actually carried IP payload, but from GPRS onwards it's really a packet-switched core infrastructure for all data service. In fact it's come full circle from LTE/EPC and beyond, as the telephone side has all gone to SIP/RTP over a fully IP network model.

You're correct on the point about PPP support on Windows 7 though. I found this out for myself as well.

That's disappointing....
