You would be better making a symlink using devd rules, something like

notify 100 {
        match "system"          "USB";
        match "subsystem"       "DEVICE";
        match "type"            "ATTACH";
        match "vendor"          "0x0403";
        match "product"         "0x6001";
        action "ln -s /dev/$cdev /dev/mydevice";
};
