I read in a Linux Journal article that discussed writing usb drivers for a
LED device that mentioned an application called USB Snoopy.  It's like
ethereal for the USB bus allowing you to dissect the traffic going and
coming on the USB bus.

Good luck with that!

I read in a Linux Journal article that discussed writing usb drivers
for a LED device that mentioned an application called USB Snoopy.&nbsp;
It's like ethereal for the USB bus allowing you to dissect the traffic
going and coming on the USB bus.

How would I go about spying on USB traffic so that I can reverse-engineer a device? I have a screen-locker wireless dongle with a matching small CR2032-powered transmitter, and I believe it appears as a joystick (!)
