Hi I saw earlier mailing lists which says about the releasing the hid driver using "unbind", so what I did here now is, " echo -n /sys/bus/usb/driver/usbhid/bind" from the command line Then I compiled the usbmouse.c as it is whithout changing anything of that file. Now I got usbmouse.ko module. Next I inserted that module using insmod usbmouse.ko. Then I went back to /sys/bus/usb/devices/ and given the command " echo -n 4-1.1.1 > /sys/bus/usb/drivers/usbmouse/bind So now the mouse device is regsistered with usbmouse cat /proc/bus/usb/devices/ gives the below out put C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA I:* If#= 0 Alt= 0 #EPs= 1 Cls=03(HID ) Sub=01 Prot=02 Driver=usbmouse But when I see the dmesg and cat /proc/kmsg mesagges continuosly usb_mouse_irq is getting called without even any mouse clicks when I saw the status of urb->status it is -84 (EILSEQ) and usbmon capture is showed below one <URB Tag> <Timestamp> <Event Type> <Address> f02e5c80 150582594 S Ii:4:010:1 -115:8 4 < f02e5c80 150606583 C Ii:4:010:1 -84:8 0 f02e5c80 150606601 S Ii:4:010:1 -115:8 4 < f02e5c80 150630578 C Ii:4:010:1 -84:8 0 f02e5c80 150630594 S Ii:4:010:1 -115:8 4 < f02e5c80 150654576 C Ii:4:010:1 -84:8 0 ... ... above message is continuously recieving after binding the device But am able to reicieve the device details properly like vendor id , product id and all remaining things Is any thing wrong am doing or my approach itself not correct.
