how to know the irq of a device?

[hictio]

how can i know what irq is using my /dev/mouse? i`m asking because i have a ps/2 one, and for what i read at the `bus mouse how-to` that type of device must and only use irq 12. since my mouse -under gpm- doesn`t work, i wonder if the irq is incorrectly set.
thanks in advance.

Try typing:

more /proc/interrupts

This will list the interrupt usage on your sustem. You should see something like:

 0: 2246814129   timer
 1:     263683   keyboard
 2:          0   cascade
 4:          4 + serial
 8:          2 + rtc
11:  109617925   eth0
12:    2491811   PS/2 Mouse
13:          1   math error
14:   10566931 + ide0
15:      24936 + ide1

Hope this helps. -mk
