generating keyboard events from userspace

[Philip Lawatsch <philip@lawatsch.at>]

Hi,

I'm currently writing an userspace application (with libusb) which 
handles the LCD display on a logitech g15 keyboard.

This keyboard consists of two usb devices + a usb hub. One device is the 
normal keyboard and the other device is the lcd + the special keys.
Both devices get detected by the usb-hid driver.

Now the problem is that in order to access the lcd from userspace I have 
to detach usb-hid driver from the interface so I can use it. (Or, I'd 
have to write a driver for it which I'd like to avoid).

So, is there any way to "inject" events generated by pressing the keys 
on the device I'm handling myself back into the whole system from userspace?

I'd really like to avoid writing a kernel mode driver for this.

Any help would be appreciated (even redirecting me to a more suitable 
mailing list, I didn't find any)

kind regards Philip
