Ok - then I'm running out of ideas. Have you set the language correctly in LE config and Kodi and does the keyboard work correctly in ssh?
Display MoreThere's an eventlircd udev rule with the USB id (idVendor=04f2, idProduct=0618) of your wireless HID receiver, so LibreELEC will treat your keyboard/mouse as a remote.
Can you copy /usr/lib/udev/rules.d/98-eventlircd.rules to /storage/.config/udev.rules.d/ and then remove these 3 lines?
CodeENV{ID_VENDOR_ID}=="04f2", ENV{ID_MODEL_ID}=="0618", \ ENV{eventlircd_enable}="true", \ ENV{eventlircd_evmap}="topseed.evmap"
As an easier alternative to editing the rule you can test with eventlircd disabled, run systemctl mask eventlircd - but note that then IR remotes won't work properly.
Not exactly sure why this udev rule was added about 7 years ago eventlircd: add support for more Chicony and Topseed remotes · LibreELEC/LibreELEC.tv@c73b3bb · GitHub - in OpenELEC 0.99 days - probably the same receiver is/was also used for some wireless remote.
The rule seems to be too unspecific. The receiver registers many input devices, the rule matches all, but should only match the one used for remotes. We'll have to think about the best way to fix that.
so long,
Hias
I'm so sorry for the wait.
First of all, thanks both for the help but thanks so much HiassofT, the solution that you give me works perfectly.
I copied the file you said me and then I removed the 3 lines, I restarted the TV Box and now my keyboard works perfectly with Libreelec, thanks.
