Looking further down, the commit that creates the problem is (thanks to

commit ef513be0a9057cc6baf5d29566aaaefa214ba344

Author: Jim Lin <[email protected]>
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.

--- Comment #4 from Vincenzo Di Massa ([email protected]) --- 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

Quoted 11 lines

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

bug 207065, comment 7 contains two patches to fix the problem.

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.
