Sorry, I mis-spoke for the sockit. I have to turn dcache off for USB to
work reliably.

=> dcache off
=> usb start
starting USB...
USB0:   Core Release: 2.93a
scanning bus 0 for devices... 2 USB Device(s) found
=> usb tree
USB device tree:
  1  Hub (480 Mb/s, 0mA)
  |   U-Boot Root Hub
  |
  +-2  Mass Storage (480 Mb/s, 200mA)
       SanDisk Firebird USB Flash Drive 4C532000040115111005

=> version

U-Boot 2016.03-rc3 (Mar 02 2016 - 17:00:25 -0600)
