Tested on Venice2, Jetson TK1, and Big with a variety of USB2.0 and
USB3.0 memory sticks and ethernet dongles using controller firmware
recently posted by Andrew Chew [2].

I have had mixed results when testing this on a Jetson TK1 board. Of 8
USB devices I tested with, about half where probed correctly, but the
other half repeatedly fail in hub_port_init because in the GET_STATUS
right after the reset, the C_PORT_CONNECTION bit is set.

I don't see any correlation between the failure and the kind of usb
device, but I don't have much experience with USB implementations
either.

Hmm... I haven't seen that before.  Which particular devices were you using?

Here they are:

work:

Genius keyboard: 05d5:6782
Logitech mouse: 046d:c06a
Denver MP3 player: 10d6:1100
Atheros Bluetooth dongle: 0cf3:3005

don't work:

MCS7830 ethernet dongle: 9710:7830
Genesys Logic hub: 05e3:0608

I tried the hub and it works just fine for me... Have you tried this
on any other boards like Big or Blaze?
