As you said AckAck's suggestions are decent companies, that's always a good starting point and mostly a sign of sufficient yet cost effective quality.
As for Power Management, I'd choose "Best Performance" for gaming. I'd also look at the Advanced settings. This little piece of advice was something I found while checking my own settings for translation:

For testing, use an inexpensive USB extension cord which you can splice and strip as much as you wish without sacrificing your precious pedals. Avoid shortcuts, though, they may ruin both your computer and the controller!
Last but not least, don't tinker before you've tried with the powered hub. If that fixes your problem, that's it. There's not too much juice in USB ports anyway, especially not in laptops, so the culprit is most likely there. See
