A lot of the cheaper network stuff (both wired and wireless) is actually repackaged and rebranded. Wireshark and drivers will usually be for the original chip rather than for the name on the box. It's easy enough to see the chip on a PCI / PCIe card, but obviously you don't want to go opening up USB stuff. If you can find a utility that lists off the device identifiers (e.g. in Linux "lsusb") that can help in working out what driver you need or what it will be called in wireshark etc.
Plugging in the FCC ID into the EAS search
is also handy for determining the chipset.
