commit ef513be0a9057cc6baf5d29566aaaefa214ba344
Author: Jim Lin <jilin@nvidia.com>
Date:   Mon Jun 3 18:53:44 2019 +0800

    usb: xhci: Add Clear_TT_Buffer

    USB 2.0 specification chapter 11.17.5 says "as part of endpoint halt
    processing for full-/low-speed endpoints connected via a TT, the host
    software must use the Clear_TT_Buffer request to the TT to ensure
    that the buffer is not in the busy state".

    In our case, a full-speed speaker (ConferenceCam) is behind a high-
    speed hub (ConferenceCam Connect), sometimes once we get STALL on a
    request we may continue to get STALL with the folllowing requests,
    like Set_Interface.

    Here we invoke usb_hub_clear_tt_buffer() to send Clear_TT_Buffer
    request to the hub of the device for the following Set_Interface
    requests to the device to get ACK successfully.

Hello, please have look at bug 206897, they look related.


Bug 206897, comment 21 asks to provide logs with the following procedure...
maybe we can anticipate it here for our device. Let's see who gets the job done
faster :-)


### Detailed log generation procedure from Bug 206897, comment 21

> Also traces and logs with more usb details enabled could be useful.
> These can be taken with any recent kernel.

> mount -t debugfs none /sys/kernel/debug
> echo 'module xhci_hcd =p' >/sys/kernel/debug/dynamic_debug/control
> echo 'module usbcore =p' >/sys/kernel/debug/dynamic_debug/control
> echo 81920 > /sys/kernel/debug/tracing/buffer_size_kb
> echo 1 > /sys/kernel/debug/tracing/events/xhci-hcd/enable
> < connect the logitec device >
> Send output of dmesg
> Send content of /sys/kernel/debug/tracing/trace

Hi, I tried your patches and I can confirm that the graphical tablet is now
recognized and the pen works; I've not tested all the features, but I think
that you have probably hit the right spot.
