ok. try the steps using extkbd. delete bluemaemo. install extkbd. delete the former pairing. make sure the conf is right with input deleted from the disable plugins line. start stop bt. pair keyboard. open extkbd and make sure you see the keyboard name in gui. select. i see you did most of these steps but try this again. oh..and sometimes using ext kbd ive experience the keypress not registering you discribe after idle. after i switch my keyboard to generic 105 no problem. and disable the onscreen keyboard in settings and close hardwar keyboard. try this and let me know.i just deleted my pairing and reconnected and it works fine again. im also using cssu.
