Also even if the usb 3.0 does allow for more power, you are still limited by the hubs power limits. So a higher hashing, more power hungry usb stick would only mean less sticks per hub making the usb sticks even less usefull since extra hardware costs basically just doubled. And what about heat? Tese things get pretty hot as it is. Adding another chip would take it closer to requiring active cooling per stick.
What about the smaller nm asic chips though. Dont they use less power? I doubt it would be enough for usb powered status but maybe

or lower the volts/tuning and do the 2 chips to hash at 500mhs .
I used to do it with my 22 gpus. my hd7970's would hash at 500mhs .9 volts rather then 625-660 mhs 1.1 volts.
a 1 gpu pc could hash at 500mhs with a 155 watt pull. crank it to 250 watts it would hash at 630 mhs. if you did 2 chips and altered each chips power draw it could work. I would far prefer a setup where a stick hashed at 500 mhs then 336 mhs
The lid on one of the plastic cases was cracked in half, must have been that way from the factory because the box was sealed(of course) and the box looks OK. That is, it must have been cracked before they boxed it. No worries, just info I thought you might like to have.
