These specific dmesg messages are from a 4.10.0 kernel, but 4.12,
4.13, 4.13.1 and 4.13.2 have the same problem. Here's the output from
a 4.13.2 kernel:

Hello all,
I have a Seagate External HDD PN: 9sean2-500 that works fine on USB2.0
ports (and older kernels) however when connected to usb3.0 port on
newer kernels, the drive fails any write access.

Greetings,
I'm trying to find the simplest way to develop a bulk mode gadget that
exposes a standard userland IO interface. I've not been able to find
anything suitable but if such a beast does exist please do point me in the
right direction. Failing that please read on.

Hey,
I recently bought a Thinkpad T470 notebook and added the Fibocom
L831-EAU WWAN card. It's mbim-based, but unfortunately I can't get it to
work correctly. In fact I'm experiencing similar issues to Patrick
Chilton, who reported this behaviour a few months ago also on this list:

Hello!
TL;DR:
I'm having troubles with Dell WD15 dock connected to USB-C of Dell
Precision 5520 laptop.
I'm seeing very frequent kernel freezes, sometimes panics,
particularly on logging into the desktop session.
I first created a ticket on Ubuntu Launchpad, but I have been directed
to here. https
Primarily it was intended to just add USB2517 hub support to the driver.
But after tests a bug and inconistency were discovered. So it was decided
to make the following changes:
Changelog v1:
- Add USB2517/i hub specifics support to the driver
- Fix property_u32 NULL-pointer dereference
- Add new
There are USB2517 and USB2517i hubs, which have almost the same
registers space as already supported USB251xbi series. The difference
it in DIDs and in few functions. This patch adds the USB2517/i data
structures to the driver, so it would have different setting depending
on the device discovered o
USB2517 got three additionl downstream ports, which can
as well be mapped to another logical ports. USB2551xb driver
currently doesn't fully support such setting configuration
from dts file. This patch doesn't change this, but adds
usb2517 spcific ports default liner mapping.

USB251xb as well as USB2517 datasheet states, that all these
hubs differ by number of ports declared as the last digit in the
model name. So USB2512 got two ports, USB2513 - three, and so on.
Such setting must be reflected in the device specific data
structure and corresponding dts property should
Battery charging settings are supported by USB251xb hubs only.
USB2517i isn't one of them. So we need to reflect it within the
device-specific data structure. The driver doesn't support dts
property to change this setting, but instead defaults it with zero.
So the flag isn't used anywhere in the dr
USB electrical signaling drive strength boost bit is also supported
by USB2517 hub. Since it got three addition ports, the designers
needed to add one more register for initialization. It turned out
to be formerly reserved 0xF7. As before we just initialize it with
default zeros.

The driver used to be developed with legacy GPIO API support. It's
better to use descriptor-based interface for several reasons. First
of all the legacy API doesn't support the ACTIVE_LOW/HIGH flag of dts
nodes, which is essential since different hardware may have different
GPIOs connectivity inclu
The methods like of_property_read_u32 utilizing the specified
pointer permit only the pointer to a preallocated u32 storage as the
third argument. As a result the driver crashes on NULL pointer
dereference in case if "oc-delay-us" or "power-on-time-ms" declared
in dts file.

USB2517 supports two LED modes: USB mode (default) and speed indication
mode. The last one can be switched on by corresponding dts property.
Since USB251xb hubs doesn't support LEDs settings, we need to ignore
this setting.

This parameters may be varied in accordance with hardware specifics.
So lets add the corresponding settings to the usb251x driver dts
specification.
