ALinuxUser, Xiaofan Chen's example was unbinding the usbhid driver via the /sys/bus/usb/drivers/usbhid/unbind control file -- yours is using /sys/bus/usb/drivers/usb/unbind instead. You probably have to use the control file that corresponds to the driver your device is using. (Check lsusb -t output.)
