    Hi @kaveh rahimi ,
    Add reference to 'System.Management', then try the code like: 

            Dim theSearcher As ManagementObjectSearcher = New ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE InterfaceType='USB'")  
  
        For Each currentObject As ManagementObject In theSearcher.Get()  
            Dim theSerialNumberObjectQuery As ManagementObject = New ManagementObject()  
            theSerialNumberObjectQuery.Path = "Win32_PhysicalMedia.Tag='" & currentObject("DeviceID") & "'"  
            MessageBox.Show(theSerialNumberObjectQuery("SerialNumber").ToString())  
        Next

    Hope it could be helpful.
    Best Regards,
    Xingyu Zhao
