I suspect we are not able to fix it via Kconfig as we really don't
know if a system uses ULPI interface or not via Kconfig perspective.

Thanks, Shawn!
Peter,
Could you please then queue this chipidea patch for 4.18-rc?
Thanks

Control_config is a group under gadget that acts
as a normal config group, except it does not
appear in cdev->configs.
Functions that have exactly zero descriptors can
be linked into control_config. These functions
are bound and unbound with the rest of the gadget,
but are never enabled. Also,
This flag allows users to directly specify when
they want a ffs instance to be used for handling
control requests only via the configfs control_config/
group. When the flag is set, user must set *none*
of the speed descriptor flags and provide no
speeds in the descriptor. This ensures that it

Vendor specific control requests are a significant category of
USB communications. With the current framework, it is difficult
for a composite gadget to handle these requests since any
function could be active. This patchset/feature allows all
unhandled control requests to be passed to a singular

Commit 1b9ba000 ("Allow function drivers to pause control
transfers") states that USB_GADGET_DELAYED_STATUS is only
supported if data phase is 0 bytes.
It seems that when the length is not 0 bytes, there is no
need to explicitly delay the data stage since the transfer
is not completed until the

Corsair Strafe appears to suffer from the same issues
as the Corsair Strafe RGB.
Apply the same quirks (control message delay and init delay)
that the RGB version has to 1b1c:1b15.
With these quirks in place the keyboard works correctly upon
booting the system, and no longer requires reattaching

pm_runtime_put_sync() gets called everytime in xhci_dbc_stop().
If dbc is not started, this makes the runtime PM counter incorrectly
becomes 0, and calls autosuspend function. Then we'll keep seeing this:
[54664.762220] xhci_hcd :00:14.0: Root hub is not suspended

Hi,
I am getting coverity reports because usbnet checks for zero length
transfers before it allocates buffers. Is the assumption that no
buffer is needed actually correct for every HCD and should I document
this?

Hello Felipe,
We have discovered an issue in MUSB gadget when receiving control OUT
transfers. I have specifically observed it very frequently on the second
SET_CUR UVC request when trying to stream video with yavta from a UVC
gadget.
What happens is that in the DATA phase, the controller copies
