In contrast to Philjolet's experience, I tried a Jitterbug in an unused USB input on my Lenovo XP laptop. The Jitterbug worked fine from the start and firmed the bass while improving the focus and image density of the instruments. Now I always go "Bugged"!
That being said, my friend bought one and it worked on a mutual friend's computer but not on his computer. And a different Jitterbug that the same mutual friend loaned him worked fine--so they traded JitterBugs and it solved the problem. I can't explain it, but that's what happened.
