A lenovo usb keyboard with a new HID_NAME

[hrimfaxi]

Hi, I found out this utility even works with lenovo USB keyboard LXH-JME2209U. My Fn lock is successfully unlocked! Nice work!
However, its HID_NAME was "Lenovo Lenovo USB Keyboard". Maybe you could handle it too in the script.

# cat /sys/class/hidraw/hidraw2/device/uevent

HID_ID=0003:000017EF:00006018

HID_UNIQ=

Addition: seems only tp-compact-usb-keyboard.c works.

Okay, makes sense that only tp-compact-usb-keyboard works, given it's the same with the Lenovo USB keyboard I have. You could copy the top of the script into a new script that wraps around tp-compact-usb-keyboard.c if you wanted the auto-keyboard-finding functionality. Ideally we'd poke support for the keyboard into the Linux kernel though.

What hidraw device are you sending commands to, hidraw2 or hidraw3 (assuming you haven't unplugged anything since the above dmesg)? I'm guessing (well, more hoping) that it's the latter device, hidraw3, that works. Do all the special Fn-Key functions work properly if you use evtest on the linux console (i.e. outside X11)? Some might only be available on the second input device for the keyboard.

Does the keyboard have a pointing device of some kind too? It's hard to find out any information on it, best I can do is guess that it's the keyboard pictured here: http://www.newegg.com/Product/Product.aspx?Item=N82E16883108568

Yeah I already done that part for udev to call tp-compact-usb-keyboard.

Either hidraw2 or hidraw3 works if I unplugged then plugged it back. It works even only one single hidraw device was given to tp-compact-usb-keyboard.

This keyboard have no pointing device. It was the keyboard shipped with Lenovo server and PC sold in China.
And quickly became a nightmare for people working on Linux with it.

Here is the result of xev | grep --line-buffered -A6 KeyRelease after running tp-compact-usb-keyboard /dev/hidraw3:
I think from F1 to F12 all keys are unlocked.
