I started to see usb failures on i.MX6, like "nonzero urb status received" after:
" commit 4e88d4c083016454f179686529ae65d70b933b58

usb: add a flag to skip PHY initialization to struct usb_hcd"
The errors were related to some scpecific scenarios, like usb device reset, disappear etc.
The fix below worked for me.
