...and both Wireshark and tcpdump can, at least on Linux, capture on both
Bluetooth and USB if the machine on which you're capturing has:
1) a sufficiently recent version of libpcap (1.0.0 or later, although,
for USB, you probably want 1.1.0 or later) that was configured with USB and
Bluetooth support - whether you have that is up to the makers of your Linux
distribution, although you could try configuring and building libpcap yourself
and either rebuilding tcpdump/Wireshark/whatever with it or building it and
installing it as a replacement for the distribution's libpcap shared library);
2) a Bluetooth or USB stack in the kernel that supports the capture
mechanism used by libpcap.

This is the tcpdump-workers list.
