How to read keys from USB keyboard on AT91SAM9260

siva4ever · 08-25-2009, 01:50 AM

Hi Everyone,

I am using 2.6.26.3-olimex kernel(Embedded system) running on AT91SAM9260. I am using a Logitech USB keyboard.

It is detected as "/dev/input/event0".

I don't know how to detect key press events and read the keys?

Why can't I read the keys using scanf() like funtions?

Can anyone help me?

Regards,
Siva

Have you got HID modules loaded?

Hi business_kid,

Thanks for your response.

I have enabled the following options in the menuconfig file.

Input Device Support --> Event Interface
Keyboards --> AT Keyboard
HID Devices --> USB Human Interface Device support
HID Devices --> PID device support
Special HID Drivers --> Logitech and Logitech force feedback

I don't find anything inside /lib/modules/

How to check the HID modules are loaded or not?
