Q: Does JitterBug require a device driver installation?
A: Nope. JitterBug is a passive device. There are no active circuits or logic systems.

Q: How many Jitterbugs can I use on my computer?
A: In our observations, we have found that positive improvements are obtained with up to two parallel JitterBugs per USB bus. For example, a typical laptop will have two to three USB ports, but only one bus. So, using two JitterBugs and leaving the third port open will yield positive results, but installing a third JitterBug, in our opinion, takes a step backwards. When going beyond more than two JitterBugs per bus, the sound becomes dark and congested.

However, some computers may have more than one bus. Custom gaming laptops and PC towers are two examples of computers that may have more than one USB bus. In these cases, using two JitterBugs on each bus will yield extraordinary results. That said, if you don’t know how many buses are on your computer, err on the side of caution and assume there is only one bus.

Q: Will JitterBug make me smarter, thinner, taller, and more attractive?
A: Absolutely! … Not. But it will make your audio system sound fuller, richer, and far more musical, which in turn will make you far happier. And isn’t that what life is really all about?

The second Jitterbug will help, but not as much as the first one. If you're going to be using this rig while traveling, I would just use the one Jitterbug with your Dragonfly.
