Fixing vendors that re-use USB IDs

[whot]

Summary: we need some solution that allows us to match tablets that re-use the USB IDs. Huion, Gaomon and Ugee/XP-Pen seem to be the big offenders here and in some cases we can at least string match on the device name but e.g. #609 shows that's not always possible.

cc @JoseExposito - you've worked on some of these tablets in the kernel, is there anything we can export from the kernel to identify these tablets in userspace? Like stuffing an enum into id_input->version? Or some custom udev property? Or sysfs file?

[TacticalCode]

I did some digging, with uclogic-tools (https://github.com/DIGImend/uclogic-tools) I can read details including the Firmware version off the attached device:

$ sudo uclogic-probe 1 4 | uclogic-decode 
    |           Manufacturer: GAOMON
    |                Product: Gaomon Tablet
 64 |        Params block #1: ???????????????????????????????????????????????????????????????????????????????????????????????????
    |                          Max X: 8192

    |                   Max pressure: 2301
    |                     Resolution: 2048

    |                   Max pressure: 8191
    |                     Resolution: 5080
    |
 c9 |       Firmware version: OEM02_T19m_200114
 ca |  Internal manufacturer: HUION Animation Technology Co.,ltd

Through the power of binwalk, strings and grep I found a TabletCfg.dt file in a download from the manufacturer that contains JSON data in { "FW_CODE": { "Properties":"values" } } format for 129 firmware codes, 86 of which are unique non-null firmware -> ProductName pairs like:

"OEM02_T19M": {
	"EnablePenKey0": false,
	"IsTouchHKey": false,
	"LED": false,
	"Langs": 131071,
	"MKeyConfig": null,
	"Multimedia": {
		"KeyCount": 0
	},
	"PenKeyCount": 3,
	"ProductName": "M106K PRO",
	"bMultimedia": false,
	"bOSD": false,
	"battery": false,
	"bluetooth": false,
	"dongle": false,
	"hasTitl": false,
	"hkeyNum": 12,
	"isMonitor": false,
	"isTouchMonitor": false,
	"mkeyNum": 0,
	"mouseModel": true,
	"passive": false,
	"penModel": "GM_PW205",
	"skeyNum": 16,
	"wireless": false
},

If we could read the Manufacturer/Product/Internal manufacturer and Firmware version values that uclogic-probe can read off the device, we might just be able to match some devices?

EDIT: kernel does read the firmware version, but doesn't expose it: https://github.com/torvalds/linux/blob/master/drivers/hid/hid-uclogic-params.c#L872
Their ver_ptr is only used to determine if they can go on to probe for other parameters, there are no sysfs_* or kobject references that would be needed for exposure via /sys.

AFAICT, we need a kernel patch, is anyone here friends with GregKH? :D

[whot]

Nice spotting. I wonder if we could just add a new custom uevent for the firmware version? I don't know what the politics are regarding that and/or if the infrastructure is in place.

Turns out, HUION ships a JavaScript file with similar contents in their proprietary driver.

Here is my table HUION INSPIROY H640P information:

$ sudo uclogic-probe 3 11 | uclogic-decode
    |           Manufacturer: HUION
    |                Product: Huion Tablet_H640P

    |                     Resolution: 5080
    |
 c9 |       Firmware version: HUION_T203_200720
 ca |  Internal manufacturer: HUION Animation Technology Co.,ltd

And, after some grep-ing, I found a file (res/StatuImg.js) that contains:

"HUION_T203": {
  "HBUTTON": {
    "0": "HKey1.png",
    "1": "HKey1.png",
    "2": "HKey1.png",
    "3": "HKey1.png",
    "4": "HKey1.png",
    "5": "HKey1.png"
  },
  "ProductName": "INSPIROY H640P"
}

This JavaScript file contains 79 non-null pairs of firmware + product name. But I guess that other driver downloads might contain similar files (I didn't check it).

For reference, here is the file after some Node.js magic:

So, it look like if we could access the firmware version from user-space, we'd be able to match the right device for a good number of tablets.

[TacticalCode]

@jexposit Nice, and your USB ID (lsusb) is 256c:006d too?

I was starting to think that maybe they fixed their device IDs (#614 (comment))
But this Huion H640P user also has the same IDs: linuxwacom/wacom-hid-descriptors#322

I think I could hack up a patched hid-uclogic kernel driver to expose the firmware string via sysfs in a week or two as a PoC (but far from merge-able into the kernel), if someone can implement a PoC in libwacom? I'd need to know where to expose it in /sys, directories for the device are currently:

I don't know if libwacom has enough info to construct those paths (including bus/controller number 0003 and whatever 0006 and 0007 is), or should it be placed under /sys/bus/hid/drivers/uclogic/<vid>:<pid>/firmware? That wouldn't account for multiple devices attached at the same time though (even if that should be a niche use case, who dual-wields graphical tablets?)

[whot]

I don't know if libwacom has enough info to construct those paths

Where the device is created from a device path (libwacom_new_from_path(), e.g. GNOME's mutter and control-center) we have access to the udev device so we can run up and down the tree to find whatever we need, regardless where you're trying to hide it ;)

Definitely needs to be in the /sys/devices part though to get accepted and be useful, not in /drivers/ (which is just a symlink anyway as you can see so no point trying to make it do anything it doesn't).

[JoseExposito]

I put together a couple of patches to expose to userspace the firmware name via sysfs attribute.

To keep things simple, I cherry-picked all patches from the upstream kernel not present in DIGImend and added my patches on top. Just clone this branch:
https://github.com/JoseExposito/digimend-kernel-drivers/tree/sysfs-fw-name

In this way, you can test the changes without having to compile your own kernel. Just follow the instructions present here (basically, make && sudo make install):
https://github.com/DIGImend/digimend-kernel-drivers?tab=readme-ov-file#installing-from-source-with-dkms

After loading the new driver, you should see a read only fw_name file:

$ ll /sys/devices/pci0000:00/0000:00:01.2/0000:20:00.0/0000:21:08.0/0000:2a:00.3/usb3/3-2/3-2:1.0/0003:256C:006D.000A/

-rw-r--r--. 1 root root 4.0K Dec  9 21:00 uevent

Containing the firmware version name:

$ sudo cat /sys/devices/pci0000:00/0000:00:01.2/0000:20:00.0/0000:21:08.0/0000:2a:00.3/usb3/3-2/3-2:1.0/0003:256C:006D.000A/fw_name
HUION_T203_200720

@whot would this work for libwacom? I haven't investigated how I can find that file from libwacom yet, but if you don't have a device to test with I can try to do the libwacom part.

[whot]

Nice! g_udev_device_get_sysfs_attr() should pick it up then, needs to be added to get_device_info() and then the rest should be a breeze. Note that the device is the evdev device so you might have to do a g_udev_device_get_parent() loop (just hook into the existing one for the name attribute).

[jexposit]

I have created a small script to extract the firmware <-> model equivalences from the HUION driver:
https://github.com/JoseExposito/uclogic-firmware-names

Here is the file it generated:
