| |
Hi,
Such as drivers/input/keyboard/neo1973kbd.c :
input_dev->name = "Neo1973 Buttons"; input_dev->phys = "neo1973kbd/input0"; input_dev->id.bustype = BUS_HOST;
As i understand , application will access /dev/input/neo1973kbd/input0 as input handler such as open(/dev/input/neo1973kbd/input0) . I want to know which minor number will be used by input0 , because event0 will use minor number 64 . Assume no minor number for neo1973kbd/input0 ,how the driver process open(/dev/input/neo1973kbd/input0) ? because no major and minor number related to it .
ls -l /dev/input/ crw-r----- 1 root root 13, 64 2009-03-20 08:54 event0
Thanks in Advanced . Best Regards. Peter Meng
