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,

May I use 'reported device ids hash' instead of serial number in device manager?

Hi @kaveh rahimi ,
Not sure you can get 'reported device ids hash', do you consider getting the 'PNPDeviceID' of USB?
Here's the code you can refer to.

        Dim theSearcher As ManagementObjectSearcher = New ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE InterfaceType='USB'")  
  
        For Each currentObject As ManagementObject In theSearcher.Get()  
            Console.WriteLine($"{"PNPDeviceID"}-{currentObject.Properties("PNPDeviceID").Value}")  
        Next
