    You can easily remove execute permissions with chmod
    chmod -x /dev/sdb1
    assuming your Usb is /dev/sdb1. But anyone can change that, encryption is the only way to do what you're asking.

    thanks for ur reply.

    my problem is,

    I am able to block(allow) or unblock(reject) the USB mass storage device to my pc with the help of libusb api's. upto this ok.

    incase of unblock(accept) device:
    i want to control write/read to/from device.
    means, i need a control (accept/reject transfer) when user copy a file from my pc and paste in a usb mass storage (pendrive) device.

    I am not able to achieve with LIBUSB API's. Please

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    If you format the device with a Linux file system, such as ext2/3/4, then you can set ownership and permissions on the files as you wish, or if you have SELinux extensions on your system, you can add them to the appropriate ACLs (Access Control Lists). In any case, Windows users will not be able to easily access the data.
    Sometimes, real fast is almost as good as real time.
