Question My driver for mouse gives irq no. error, device busy


I got the code for mouse device driver from net and was interested to implement it for my mouse. when i compiled it i got a device busy, irq no. not available error. I'm using irq no 5 for my mouse. please help as to how i choose the correct irq no for my mouse.


I'm just very much confused. I'm new to driver programming and keen to test mouse. Got driver from a site and few steps to insert it. But finding it confusing. Please help to insert my mouse and test it. Please give me the steps to do it. My driver is for serial PS/2 mouse.

Moved: This thread is more suitable in Linux-Newbie and has been moved accordingly to help your thread/question get the exposure it deserves.

In the file /proc/interrupts you have an interrupt list. Is no 5 taken by any other driver? But I think that the problem is connected with 'device busy'. It looks that something is already using the mouse (old driver, maybe?). Which port are you using for your mouse?
