From your other question, you're running on Windows XP.
As I explained in the answer to that question, you can't select your 3G modem as an interface on Wireshark on Windows XP:
The problem with your 3G modem is that it's a "WAN" device from the standpoint of the Windows networking stack, and those devices connect to the rest of the networking stack in ways that don't work very well with the way the WinPcap driver plugs into the networking stack. They show up as PPP (point-to-point protocol) devices, and, as the answer to Q-5 in the WinPcap FAQ says, "Windows XP (x64)/2003 (x64). It's not possible to capture on PPP/VPN connections on these operating systems.", so you're not going to be able to capture regular networking traffic on your 3G modem with Windows XP and programs using WinPcap (such as Wireshark) - no matter what version of Wireshark you use.
You may be able to capture the raw USB traffic to and from the 3G modem; whether it will be possible to extract the contents of packets from that USB traffic using Wireshark is another matter.

Does "w." stand for "Windows" or "Wireshark"?
If it stands for "Wireshark", on what operating system are you running Wireshark?
Along with the Wireshark version, and the capture library used. All this info is in the Wireshark Help -> About Wireshark dialog.
