Lenovo Essential Wireless Keyboard doesn't works (Primax Electronics manufacturer)

[Julian Alarcon]

Hi
I got an issue on Ubuntu 18.04 with latest packages.
uname -a:
Linux MyLaptop 4.15.0-20-generic #21-Ubuntu SMP Tue Apr 24 06:16:15 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

My wireless keyboard is not working, Ubuntu only recognize some special keys (Super, Ctrl, Shift, Alt)

This is a Mouse+Keyboard combo using a wireless receiver by usb:

lsusb:
Bus 001 Device 005: ID 17ef:609b Lenovo

Mouse works fine, and in Windows 10 it works with no issues.

I found multiple reported problems with this keyboard in other distros (and from Asus too, as the real manufacturer is Primax Electronics).

There is a workaround (I still didn't tried) but it needs to compile an specific driver.

There is already a kernel report about this.

Hello,

I have a Lenovo Professional Keyboard combo which is not working on Linux because it sends an extra byte (0x71) for each key.

Some people explains the situation in the followings links:

https://forums.lenovo.com/t5/Linux-Discussion/Professional-Wireless-Keyboard-not-working-on-Linux/td-p/3726486

https://github.com/y-trudeau/linux_lenovo_ultraslim_plus

Do you think it's possible to make usb keyboard driver able to understand this extra byte?

All USB bugs should be sent to the <email address hidden> mailing
list, and not entered into bugzilla. Please bring this issue up there,
if it is still a problem in the latest kernel release.

Description of problem:

I bought new wireless keyboard for my Lenovo laptop (T470s) with mouse. The mouse works, but the keyboard doesn't. Only keys "super" and "alt" react on the keyboard. It is really pity, because i would like to use it.

Strange is that the keyboard works in bios and in grub. Same problem I have with Fedora 26.

We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. As kernel maintainers, we try to keep up with bugzilla but due the rate at which the upstream kernel project moves, bugs may be fixed without any indication to us. Due to this, we are doing a mass bug update across all of the Fedora 27 kernel bugs.

Fedora 27 has now been rebased to 4.15.3-300.f27. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.

    HID: support primax keyboards violating USB HID spec

    Primax keyboards with the issue this driver addresses report modifier
    keys as in band key events instead of as out of band modifier bits,
    resulting in the modifier keys generating key up events immediately
    before the keys they are intended to modify. This driver rewrites
    the raw report data from such keyboards into USB HID 1.11 compliant
    report data. It only matches the USB vendor and product IDs for the
    keyboard it has been tested on. Since there are several keyboards,
    notably a number of laptops and folding USB keyboards known to have
    similar unresolved problem reports, the list is expected to grow.

$ git describe --contains f6a04605f3038
v3.2-rc1~187^2^2~2

Currently the driver only supports the device ID 0461:4e05 and will need the IDs of other devices adding in order to work with them.

# extract from drivers/hid/hid-primax.c

static const struct hid_device_id px_devices[] = {
    { HID_USB_DEVICE(USB_VENDOR_ID_PRIMAX, USB_DEVICE_ID_PRIMAX_KEYBOARD) },
    { }

$ grep PRIMAX drivers/hid/hid-ids.h

#define USB_DEVICE_ID_PRIMAX_KEYBOARD 0x4e05
#define USB_DEVICE_ID_PRIMAX_REZEL 0x4e72

Collecting additional IDs and adding them would be the best action to take.

"Currently the driver only supports the device ID 0461:4e05 and will need the IDs of other devices adding in order to work with them."

Here are device IDs for a few models that I have found among the many reports of similar problems with Primax wireless keyboard + mouse combos:

0461:60a9 - Lenovo Wireless Essential
0461:609b - Lenovo Wireless Professional
0461:4e80 - Asus Keyboard and Mouse
0461:4e90 - HP Pavilion Wireless Keyboard and Mouse 800

I have the HP model. What's the proper way to make sure these are added in the future?

[Kai-Heng Feng (kaihengfeng)]

Follow commit f6a04605f303852963f3f357d19b967aa83c172f and adds your ID should be suffice.
I can make a patch and build a test kernel if you like.

[John Johansson (jkej)]

Ok, I think I understand how to add IDs to the code. What should I do with the modified code? Commit and do a pull request?

Should I only add the ID for the keyboard that I have and can test (the HP one) or should I also add the other ones?

While researching the problem, I also found someone else who had been trying a fix similar to this:
https://unix.stackexchange.com/a/402288
They also seemed to add some additional code, mainly for the Lenovo keyboards. Would any of that be relevant to add too?

Yes, I'd be very thankful if you could help me produce something I can test.

[Kai-Heng Feng (kaihengfeng)]

John, please test this kernel:
https://people.canonical.com/~khfeng/lp1771431/

[John Johansson (jkej)]

Kai-Heng: I just tested your kernel, but it didn't solve the keyboard issue. However, it seemed to screw up the mouse, which of course has the same vendor and device id, since they operate through the same usb connector. With this kernel the mouse was making large erratic jumps and generating click events when I was just moving the mouse.

Is it possible that the fix was somehow modifying the report data coming from the mouse instead of the report data coming from the keyboard?

[Kai-Heng Feng (kaihengfeng)]

John, please file a new bug report and let's continue or discussion there.

Keyboard still doesn't work. Fedora 30 - Kernel 5.0.13-300.fc30.x86_64.

[Julian Alarcon (julian-alarcon)]

This is finally fixed! I test it in Ubuntu 18.04 kernel: 4.15.0-64, Ubuntu 18.04.3 kernel: 5.0.0-29.

The keyboard and mouse seems to work fine with no issues! I had to disable a workaround used to make it work! https://github.com/y-trudeau/linux_lenovo_ultraslim_plus
