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
Alcor flash drive: 058f:6387
JMicron SATA bridge: 152d:2329

I have the same SATA bridge and it is enumerating fine for me, but
I've ordered the hub as well and will check that out.

Did you have any other patches applied when testing these?

Here is the branch, including the .config I used:

http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=3.17rc4-xhci

Were you
using either SATA or PCIe at the same time?

Nope, haven't even tried those yet.

Just trying to figure out
if there's anything else different between our setups.

Yeah, I'm afraid I don't have any good suggestion to make. But maybe you
will find some error on my part in how I have applied the patches or in
the config.

Tomeu
