next in thread | raw e-mail | index | archive | help
I have this mouse that also defines the usb keyboad with 2 buttons.
Below is USB log I get when I press one of the buttons. Looks like
scancode is 0x27 (another one being 0x28).
However, ukbd device doesn't return anything. ukbd0 (and atkbd0) are
connected to kbdmux0. Signals from atkbd0 are visible through DTrace on
kbdmux0. But USB keyboard signals just disappear.
While troubleshooting, I set DTrace probes on all ukbd_... functions in
kernel. See below what is called when keyboard is datached (first), and
attached again (later). No functions are called in ukbd module when the
keyboard buttons are pressed.
What could be wrong?
