Hallo!

Okay, I hacked now

hid_convert_linux_buttons_to_numbers(__u16 linux_code, char *hid_code) { if(linux_code == KEY_ESC) sprintf(hid_code,"key_esc");

... }

in the file hid_linux.c and it works now (as here in the example for the esc button).

So, now for the lookup:

in hid_get_events(); You'll need to implement a function that does a
table lookup using the event code define(i.e. KEY_A) and translates it
to a lowercase string/symbol name "key_a". This table should be
auto-generated from /usr/include/linux/input.h. I think the table
should include all KEY_? types there (KEY_ESC -> KEY_MEDIA).

what should be the name of that function and in which file? And when should this function be called?
