Hi: What device node should I use to get input from USB keyboard in arm9 kerne? My at91rm9200 CPU recognizes the keyboard (kernel 2.6.16):
# usb 1-1: new low speed USB device using at91_ohci and address 2 usb 1-1: Product: Dell USB Keyboard usb 1-1: Manufacturer: Dell usb 1-1: configuration #1 chosen from 1 choice input: Dell Dell USB Keyboard as /class/input/input0 input: USB HID v1.10 Keyboard [Dell Dell USB Keyboard] on usb-at91-1 It is registered with proc: # cat /proc/bus/input/devices I: Bus=0003 Vendor=413c Product=2003 Version=0301 N: Name="Dell Dell USB Keyboard" P: Phys=usb-at91-1/input0 S: Sysfs=/class/input/input0 H: Handlers=kbd B: EV=120003 B: KEY=10000 7 ff87207a c14057ff febeffdf ffefffff ffffffff fffffffe B: LED=7 # cat /proc/bus/input/handlers N: Number=0 Name=kbd N: Number=1 Name=mousedev Minor=32 # The keyboard also is seen by kernel - OHCI interrupt counter increments if I hit some key: # cat /proc/interrupts ............................... 23: 26 ohci_hcd:usb1 ............................... However I cannot get access to input itself and even don't understand what device I must create to read its input. In my previous system (PPC440ep running 2.6.13 kernel) with the same keyboard handlers looked diffeent: ~ # cat /proc/bus/input/devices I: Bus=0003 Vendor=413c Product=2003 Version=0301 N: Name="Dell Dell USB Keyboard" P: Phys=usb-PPC-SOC USB-1/input0 H: Handlers=event0 B: EV=120003 B: KEY=10000 7 ff87207a c14057ff febeffdf ffefffff ffffffff fffffffe B: LED=7 ~ # cat /proc/bus/input/handlers N: Number=0 Name=mousedev Minor=32 N: Number=1 Name=evdev Minor=64 ~ # By creating device "mknod /dev/input/event0 c 13 64" I could read keyboard's input. How can I install the same handler, use "kbd" handler or by any other way read keyboard's input?
