Title:
  iphone tethering stops working quickly after connection

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Repro steps for my computer:

  1.) I use internet via iPhone USB tethering for a while, say 10 mins or less.
  2.) I notice there is no internet connection anymore.
  3.) I see these errors at syslog.

  *Re-plugging USB to same USB port changes nothing but the other ports are 
working for tethering.
  *Using different port works for a while, than same things happening. I can 
connect to internet until all USB ports disconnects the iPhone.
  *Restart solving the issue.
  *I have been encountering with this issue since a month or so.
  *I have iPhone 8 with iOS 11.2.2
