Hi,
It may just be the USB3 port has lower resistance wiring to it inside the motherboard allowing for less voltage drop, but I’d have thought the overall difference would be negligible.
It may be a wise idea to make sure the USB cable is of good quality, isn’t too long and has thick power wires.
Cheers!

Hi,
I've started to live stream a bit during the last year and just now
added headphones to the mix. I started to wonder whether my audio
interface can actually supply enough power to both a condenser mic and
a pair of headphones. I figured out that newer USB standards allow for
more power hungry devices, but does that in any way help with a USB 2.0
device?
My interface is the same old Edirol UA-25 that I've been using for a
couple of years now. It is USB 2.0 and bus powered.
It needs to supply a Røde NT-1A with phantom power and drive my new AKG
K702s at the same time. I noticed that I need to increase the output
gain a fair bit to get a good level (roughly at 50%-60% whereas I
have it at 20% with speakers).
The rig I run this on I built last year, it is based on a ASUS PRIME
B350-PLUS which provides USB 2.0, USB 3.0 as well as USB 3.1 ports
(although I can't tell which USB 3.1, way to go on that naming scheme,
my only explanation is they ran out of numbers).
I don't have other gear to compare, do you think the UA-25 can handle
it properly? Is it any help to plug it into a USB 3.0 or 3.1 port?
Best Regards,
Philipp
