This was the original mail: Hi, I was trying to mess around with the driver that drives my mouse. I found out that it is usbhid. I then added a printk statement to the init and exit function of usbhid. I then compiled and installed the usbhid drivers. Post that I ran `sudo modprobe -r usbhid` and `sudo modprobe usbhid` but couldnt observe any logs in dmesg. I am certain I am missing something fundamental. Could someone help me with this. Thanks, Rohit
