Question about video4linux.agent

[Jerry]

Dear Sir,
    Environment: Suse 9.1 professional
    Kernel: 2.6.4-52-smp
    Project: writing USB driver for CMOS sensor
    problem description:
        1. the code modified from ov511 sample source code.
        2. the driver has been registered successfully.
        3. videodev module also be installed
        4. the devices and drivers is located in /sys/bus/usb/devices and
/sys/bus/usb/drivers
            instead of /proc/bus/usb.
        5. when I execute the following code,
            rc=usb_control_msg(wis->dev,
                                              usb_rcvctrlpipe(wis->dev,0),
                                              3, //REG_IO
                                              USB_DIR_IN | USB_TYPE_VENDOR |
USB_RECIP_DEVICE,
                                              0, 0x02, &wis->cbuf[0],1,HZ);
            I got the return value of rc=-32, means Stalled(device not
responding)
            and error messages I got from /var/log/messages  is
                       linux /sbin/hotplug[4172]: no runnable
/etc/hotplug/video4linux.agent is installed.

        6. I cannot find video4linux.agent in my system.


         Can anybody help me to solve this problem ?

Thanks and Regards,
Jerry
