Ok so there is no current consumption over USB ports which could influence your netPI powering.
I searched on the Internet about "disabled by hub (EMI?), re-enabling" message and I found a lot of hits.
Are you sure this log message came during netPI runtime and not from the beginning during the standard bootup sequence? I have not analysed the netPI standard message log after a fresh restart sequence ever ... so I don't know what messages are all traced by default.
If you say you have "ethernet trouble" ... which extract trouble is this then? Is netPI no more available/reachable over Ethernet any more? Or is this just a temporarily trouble of a short time? What do you need to do with your netPI to recover from this state? Re-powering it or does it recovery by itself after a time?
Then a question to the installation position of your netPI devices? Is this a productive system under real machinery conditions with EMC and EMI? Or are your two netPIs just running in more laboratory environment?
Thx
