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. Please suggest me in this regard what am missing in usbmouse.c to get it work properly.
