What driver do I need to get RK61 BT keyboard working?

[davidshen84]

Hi,

I have a RK BT wireless keyboard. I can connect it to my Gentoo system, but nothing happens when I type. The device ID is 5c0a:0003, and lsusb shows:

I think I also need to configure a "Special HID driver" to get it working. But I just do not know which one, because it is not a common brand.

Maybe is not the most sophisticated solution but building all the drivers as modules and then watching the logs may help you to identify the right one, then you can rebuild the kernel with all the extra modules

Hope it helps,

I have same keyboard. And it work perfect especially in vim. You should read keyboard instruction before start.
If you connect RK using USB you need press Fn+TAB to switch to USB mode and Fn+TAB again to switch back BT mode.
(In rare cases you could trap in hidden NumLock mode to leave it press Fn+6)
(In BT mode Fn+P start pairing, Fn+Q,Fn+W,Fn+E select pairing line)
(Also Fn+left Ctrl switch behaviour, Fn+Win lock keyboard)
(And left Alt works differ than right Alt you can't hold left Alt but can hold right)

If you using BT connection you see different behaviour of F1-F12 so have to read this:
https://wiki.gentoo.org/wiki/Apple_Keyboard
https://superuser.com/questions/79822/h ... d-in-linux

change behaviour on the fly
# echo 2 > /sys/module/hid_apple/parameters/fnmode

or modify it in config
[/etc/conf.d/modules]
module_hid_apple_args="fnmode=2 iso_layout=0"
