This is a combination of bugs in libpcap, and you using non-kernel drivers that like to name interfaces dumb things by default.

It's in the readme under issues, but basically, if your interface has 'usb' in it, libpcap thinks you're trying to capture from a usb bus (in usb snoop mode) instead of a network interface.

You have to rename your interface by manually editing your udev rules and reloading udev. Name it something that doesn't include 'usb'. (something in /etc/udev.d/rules/ semi-dependent on distribution.)

There isn't anything Kismet can do about it, unfortunately.

No promises that it will work anyhow once you do that, I don't recall if the out-of-kernel drivers work particularly well in monitor mode or not, probably also depends on chipset.
