Greetings, I have a Belkin four port powered usb hub plugged into my RPi2 ; plugged into the Belkin hub F4U038 are two (2) Intel Edison SoC units. I am accessing the Intel Edison(s) using minicom from the RPi2 on either ttyUSB0 and ttyUSB1. This mostly works. The problem is that often these two serial connections (115200 baud) will have garbled corrupted text. For instance, holding down the 'l' key might get this: lllllllllllllltlllllllllllIUULlllllllllll3lllllllllllllllllllll2illllllllllllll
Sometimes the two serial connections work fine (rarely) and usually there is more of an issue if both SoC(s) are plugged in to the hub at the same time.
The same setup (powered hubs and SoC units) running to my notebook works flawlessly. Also, plugged into the mac works fine too. So, there is something wrong with the usb on the RPi2. I realize that the usb on the PI is 'different' / any ideas what I might try to smooth this out a bit.
I can login to the SoC(s) via wifi and that works great... and the main reason I am using the powered hub is to get mains power to the SoC units without taxing the RPi2 power supply. But sometimes it becomes necessary to get to the SoC with the serial console from the RPi2 and that's where I'm stuck.
