Question

Is there a way to read USB device serial number and data in a text file in USB using visual studio 2005?

Answer 1

Or, you can do it with much less code, here's the sample:

        string driveletter = "D:";

        var index = new ManagementObjectSearcher("SELECT * FROM Win32_LogicalDiskToPartition").Get().Cast();
        var disks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive").Get().Cast();
        string serial = "";
        try
        {
            var drive = (from i in index where i["Dependent"].ToString().Contains(driveletter) select i).FirstOrDefault();
            var key = drive["Antecedent"].ToString().Split('#')[1].Split(',')[0];

            var disk = (from d in disks
                        where
                            d["Name"].ToString() == "\\\\.\\PHYSICALDRIVE" + key &&
                            d["InterfaceType"].ToString() == "USB"
                        select d).FirstOrDefault();
            serial = disk["PNPDeviceID"].ToString().Split('\\').Last();
        }
        catch 
        {
            //drive not found!!
        }
        Response.WriteLine(serial);
