Since I no longer run Xenial, I can't directly verify the fix on that
distribution, so I'm not changing the tags. However, I'm confident the
fix will work there as well.

I am on 17.04 - I've just installed the proposed kernel (4.10.36) and
verified that it does indeed solve my problem. My keyboard works through
multiple reboots and "re-pluggings" as described above.

The "devicequalifier" kernel doesn't appear to work. It presents a
similar error either on boot or when hot-plugging the keyboard:
[ 37.680914] usb 3-3: new full-speed USB device number 5 using xhci_hcd
[ 48.097499] usb 3-3: New USB device found, idVendor=1b1c, idProduct=1b20
[ 48.097505] us
The "delayinit" kernel seems to work! The keyboard is usable when the
computer first boots, and every time I unplug and plug it back in. I did
that while following the output of dmesg -w and got the following:
[ 80.205969] usb 3-3: new full-speed USB device number 5 using xhci_hcd
[ 81.468240]
With the kernels from
http://people.canonical.com/~khfeng/lp1678477-nolpm/ , the problem seems
to have returned. I got the following error on boot:
[1.273005] usb 3-9: new full-speed USB device number 3 using xhci_hcd
[ 11.740700] usb 3-9: string descriptor 0 read error: -110
[ 11.740733]
I've also installed the linked kernel today, and verified it works for
me as well! The keyboard was detected correctly every time through
multiple unpluggings and reboots, with output similar to what Frits
pasted above. I too always get the "couldn't find an interrupt endpoint"
message, but other t
I can also confirm that I've never experienced the problem on Windows or
on the GRUB menu, both with the keyboard plugged into a single USB 3.0
and into 2 USB 2.0 ports.

I upgraded to Ubuntu 17.04 a couple of weeks ago, and the problem
persisted under its version of kernel 4.10.
I just installed all the four packages in the link above, and booted
into the new Kernel on Ubuntu 17.04. The problem still persists. This is
the output of 'dmesg | grep "usb 3-3"' shortly
For me, whether the keyboard will work or not seems random: sometimes it
works right away, sometimes it works after replugging it once, sometimes
it takes multiple attempts. The error messages are the same ones you
posted.

Title:
Kernel has troule recognizing Corsair Strafe RGB keyboard
Status in linux package in Ubuntu:

I tested it a few days ago but forgot to mark it as "Complete", sorry
about that. To further add information to my previous comment here, the
bug I described occurs both when the keyboard is plugged into a USB 3.0
port and when it's plugged into 2 USB 2.0 ports.
** Changed in: linux (Ubuntu)
Another possibly useful bit of information: I have the keyboard
connected to a USB 3.0 port - this model requires either a USB 3.0 port
or 2 USB 2.0 ports, because it draws more power than a USB 2.0 port
provides.

Tested with 4.11.rc5, and still found this issue. Took me three tries to
get the keyboard to work, with the same messages and all the same config
options as above.

Public bug reported:
I recently bought a Corsair Strafe RGB keyboard, and while it works well
when successfully recognized by Ubuntu at boot, that doesn't always
happen.
I see messages like this when booting my desktop up:
