Actually I got thinking after my earlier comment.. do you know if the 401 PT runs at 3.7v or 5v? I may have missed it but didn't see it listed on the site.
Either way I'll plug it into the wall adapter and see how it performs compared to when plugged into my usb hub but I am curious.
The 401, I am not even sure about, but prob 4v +/-
Not 100% sure of exact voltage but I can definitely say that it does hit better when plugged into the 5v usb wall adapter than it does when plugged into the regular usb hub that I have running off of my pc.
