It's powered from another plug power supply. It's one of those small ones  
I think it has some kind of transformer inside.
I'm not sure if it's isolated enough?

And big thanks to Eloy for pointing an error with the filter.

My network layout is far from perfect it's it has 3 parasite powered and 1  
powered thermometer. It's a 3 arm(2 temps on one of the arms) star with  
different lengths. Maybe it's a coincidence that I get error now. I plan  
to improve the topology of this network.

I looked at /bus.0/statistics/errors and all files except
CRC8_errors 640
CRC8_tries 46224
are 0
Is that what I should be looking for? I will compare those errors while  
using the old USB adapter.
