The sniffers for Windows don't show you what's actually going down (or up)  
the wire; they only show what the OS _thinks_ is going down the wire.

The equivalent facility in Linux is part of the kernel.  It's called
usbmon and the instructions are in the kernel source file
Documentation/usb/usbmon.txt.
