I wrote a program which have to start when the pi boots. To do this I've put it in /etc/rc.local. Unfortunately I can not get any input from the keyboard (on usb) when i press a key. Other devices (a brailledisplay on usb) are working fine.
The pi starts with autologin. Normally when i start the pi i can start the program without any problem after the autologin. The software is written in cpp and uses ncurses.
Software is used to teach young children Braille with a refreshable brailledisplay.
