Hi Kernel Experts!
My Huion 1060plus tablet is not recognized from kernel version 5.3.1

Looking further down, the commit that creates the problem is (thanks to https://bbs.archlinux.org/viewtopic.php?pid=1878478#p1878478):

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,
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.

I recently bought the tablet. If there's testing to be done, I am willing to help with it
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 :-)

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.
