Connection dropping periodically
Describe the bug The USB wired connection from EV3 to a PC running Ubuntu drops periodically .
To Reproduce Initially, I can connect to EV3 using the ev3dev-browser, then after some time, the connection drops. It seems to be indepedent of what I am doing (either using the shell or running a code, etc). Then, after some time, I can connect again. Then, it drops again. When connection drops, I cannot connect to EV3/ev3dev using ssh (directly from my linux shell) either. The EV3 was stand-alone, with all sensors and motors unplugged.
Expected behavior It shouldn't keep dropping. I used Lego's Micropython version without problem. I used ev3dev-jessie (last year) with earlier version of ev3dev-browser without any problem too.
