XP_Pen 13.3v2, almost everything works except for button 3 on stylus sends BTN_TOUCH when clicked.

[DanielJoyce]

That button appears to be sending BTN_TOUCH events along with button 1 ( the nib ). Could be a driver issue, or maybe a bad pen.

Hmm, going from the XP-Pen site, this might be intentional?

Everything else seems to work just fine.

Whats weird is right before each BTN_TOUCH event, the button 3 click produces a MSC_SCAN with value d0042, while an actual tablet touch producs d0045

Otherwise working great!

[DanielJoyce]

Also, stylus does not show up in ubuntu desktop Wacom Settings. Works, but I have to set it up manually via xsetwacom. And i can only set up the 'middle' button.

I'll get some raw low-level captures later. I suspect its something with the driver and what the tablet sends.

[spbnick]

The desktop Wacom settings won't work with those tablets unless support for them is added to libwacom, and then it probably won't that well, because Huion reuses VID:PID pairs.

By "Button 3" do you mean the top side button on the pen?

[DanielJoyce]

Yes, top half of rocker-button on stylus. I have most everything else working via a libwacom tablet-definition file, including the side express-keys. The only thing not working is the top part of the rocker button on the stylus and stylus recognition. It's sending a weird code.

[DanielJoyce]

stream.txt

Capture of button clicks, button 0 ( nib ) messages start with 07 A1, button two ( lower half of stylus rocker ) sends 07 A2, and button 3 ( upper half of stylus rocker ) sends 07 A4.

[DanielJoyce]

It comes up as UGEE brand, 0x28bd 0x000b

The product page for the XP-PEN 13.3 mentions easy one-click erasing. I'm thinking they have their tablet firmware send something non-standard for third-button click, or they provide a wonky HID descriptor and then their driver handles it special. So it might be something as trivial as providing a HID override map in the driver, or special casing the button handling.

[DanielJoyce]

Analyzing the second hid dump, I get

0x05, 0x0D,        // Usage Page (Digitizer)
0x09, 0x02,        // Usage (Pen)
0xA1, 0x01,        // Collection (Application)
0x85, 0x07,        //   Report ID (7)
0x09, 0x20,        //   Usage (Stylus)
0xA1, 0x00,        //   Collection (Physical)
0x09, 0x42,        //     Usage (Tip Switch)
0x09, 0x44,        //     Usage (Barrel Switch)
0x09, 0x45,        //     Usage (Eraser)  

So its saying it has an eraser but thats the second barrel button ( upper half of rocker ).

[DanielJoyce]

So I may be able to improve my xorg mapping, and get it working as an eraser ( as it reports eraser ), or I can submit a patch to digimend and have it remap the hid descriptor I think...

[spbnick]

Looking at stream.txt. I see absolutely normal button reports. If the driver initializes correctly, normal button clicks should be reported. However, I see that your tablet has a VID:PID pair that the driver doesn't know about and that is the problem, most likely.

I threw together a basic patch to try to support your tablet. Could you please try to download, install, and use this version of the driver to verify: https://github.com/spbnick/digimend-kernel-drivers/archive/add_xp_pen_13_3_v2.zip

Also, could you please post the output of lsusb -v for your tablet, and, please download, build, and run the fresh version of uclogic-probe from https://github.com/DIGImend/uclogic-tools/archive/master.zip Please post the output here.

Thank you.

[DanielJoyce]

Will do. I'll check it out in a bit.

It does still seem that the second rocker button is reported as eraser in the HID profile, which fits with what the website says, but may not be what people want.

[spbnick]

@DanielJoyce well, what's in HID report descriptor is entirely to the kernel to interpret, and AFAIK, there's not much, if anything, to handle buttons like that in the kernel.

[DanielJoyce]

I know, which I was wondering if the driver can remap the behavior.

Okay, so second-button right click works now, but now the xorg conf / wacom driver support doesn't get set up. lsub also looks the same.

The device usb ids look the same, so the previous tablet config should work. xsetwacom list-devices no longer lists anything though.

It appears something has subtly changed because the old x config to set the wacom driver for the device no longer seems to work.

Hmm, tablet 'works' in a generic sense. But xsetwacom still not seeing it...

[DanielJoyce]

Okay, it seems the tablet buttons are no longer working or seen by libinput at all. Would that be something done by the driver patch?

Pad and pad buttons no longer appear or work.

[spbnick]

@DanielJoyce, thank you for the detailed information, but it's a bit hard for me to follow what comes after what. Let's try to back-track a little.

I see that the driver is loading, which is good. The "interface is invalid, ignoring" message simply says that some of the USB interfaces the tablet provides don't make sense to the driver, so it doesn't add them to the system. That should be OK so far, but let's see what the pad buttons actually do.

Did I get it right, that you have the pen working with the wacom driver and everything is fine with it, but the buttons on the side of the tablet don't work? Is there anything else that doesn't work?

Regarding the buttons, please run sudo usbhid-dump -m 28bd:000b -es with your tablet connected, and press the buttons one by one, top-to-bottom, with the tablet oriented to have the buttons on the left. Post the output here.

[DanielJoyce]

Everything was working with the stock drivers that came with ubuntu 18.04 except the 'right mouse click' button on the stylus ( top half of rocker button on the stylus ). It was all picked up by the wacom drivers and working except for that part of the rocker. I just had to create the proper xorg conf file to load the wacom driver, and the wacom config file.

With the patched drivers you gave me, the tablet and pen still work in a default manner, and the right click using the top half of the rocker works now, but I can't get the wacom driver config to work anymore. None of screen buttons work either ( since wacom can no longer find the devices ). Xsetwacom list devices now only sees the pen.

Uninstalled digimend, grepping for 'hid', i see the following:

Doesn't appear to use uc-logic drivers at all. Or is it because they are compiled into the kernel? If only I could get right-click working... Is there some other maintainer I should contact?

@DanielJoyce What command do you run to get this?

[Barracuda77]

@DanielJoyce Did you manage to resolve this? I have the Artist 22E pro and facing the same issue.

[DanielJoyce]

No, I'm just gonna make do with the rocker switch being slightly 'broken' for right now. The Digimend drivers provide worse support for this tablet than the kernel drivers which seem to work fine except for part of the rocker switch.

[Barracuda77]

@DanielJoyce I managed to fix it. I am on Ubuntu 18.04 LTS I am using evdev drivers. also, I am using a udev .hwdb file to remap my tablet buttons as described here. except my scan codes are slightly different and most probably yours will be too. https://gist.github.com/loentar/1aa83e9e76fa34735133dc4d07eeb529

and to that file, I just added a command to remap that rocker as a right click. KEYBOARD_KEY_d0045=273

Edit: from your logs, I see that your rocker has the same scan code. so this line should work for you too.

[DanielJoyce]

Ahhh, awesome!!!!!! :D :D

You can add templates then to the xwacom to get gnome wacom mapping working too...

I'll dig around on that half.

Is there an upstream place to submit the evdev mappings?

[Barracuda77]

@DanielJoyce Interested to know more about the xwacom templates. update me please with that. as for a place to submit evdev mappings am still looking.

[DanielJoyce]

/usr/share/libwacom/layouts/

This where the templates are kept, stored as svgs.

https://github.com/linuxwacom/libwacom/tree/master/data/layouts

Following the above, just create a new file, add the mappings, and put in /usr/share/libwacom/layouts/

[DanielJoyce]

You just need to remap the rocker switch in your evdev hwdb entry, then once you add a libwacom config file you can remap the buttons there if you want, providing a bit more flexibillity...

Would be nice if we could remap buttons per-application, outside of said application ( some don't support it inside )...

[DanielJoyce]

I think if you get the libwacom driver working, you'll be able to really override the ctrl-shift behavior of the keys and not have to the multi-keycode remapping you're doing in hwdb, ie crippling ctrl & shift.

[DanielJoyce]

Hmm, that right-click remapping isn't working. Even after sudo systemd-hwdb update and udevadm trigger

[DanielJoyce]

Hmm, I can get d0045 to emit 273 but x doesn't pick it up.

[DanielJoyce]

Apparently its bound to the keyboard and not the device and not the mouse, while the nib and lower rocker switch is bound to the mouse.

[DanielJoyce]

Yeah, its reported on the wrong 'channel'

[DanielJoyce]

YAY!

$ cat /etc/udev/hwdb.d/10-xp-pen-keyboard.hwdb 
evdev:input:b0003v28BDp000B*
 KEYBOARD_KEY_d0045=332

Works!

332 is BTN_STYLUS2, which is 'right-click' for tablets. The events are seperate but unified by X. This works!

I noticed the lower half of the rocker sent 331, or 0x14b

#define BTN_STYLUS      0x14b
#define BTN_STYLUS2     0x14c

So I had the upper rocker button send 332 and it works! :)

[Barracuda77]

@DanielJoyce Great you made it work. Very strange as I tried 332 first and it didnt work. so I used the same code the mouse is producing and it did. obviously, each model is a little bit different.

[DanielJoyce]

What is are you using? I have Ubuntu using xfree86 with libinput and systemd.

Also I only override one code in hwdb. And I use libwacom to map everything else. Are you looking for support in one particular program?

[Barracuda77]

@DanielJoyce I am on Ubuntu 18.04 LTS Gnome using evdev drivers. I am overriding all the keys with hwdb. but it is not optimum. When I first connected the tablet to my system I had it running by libinput but it didnt work. very interested in how you use libwacom to map the rest. I mainly use Blender and 3D coat for sculpting and I use Krita occasionally for some quick sketching and rough paints.

[Barracuda77]

@DanielJoyce I tried to run it using the Wacom driver but the Gnome UI didn't recognize it. it worked but I couldn't remap any keys using the ui tool as it didn't see it. although xsetwacom list did list it.
