Can anyone tell me how to get USB serial number(Hardware ID) using VB.net?
A:
You should use WMI for this, specifically querying the Win32_USBController Class. The property you want to get is DeviceID.'
A sample WMI call in the context of a console application might look like this:
Dim mos As New ManagementObjectSearcher("SELECT * FROM Win32_UsbController")
For Each mo As ManagementObject In mos.Get()
Console.WriteLine(mo.Properties.Item("DeviceID").Value)
Next
Console.ReadLine()
You would need to add references to System.Management and System.Management.Instrumentation to use ManagementObjectSearcher and ManagementObject.

Did you add Imports System.Management to the class header?

I seriously doubt the OP wants this. The controller properties are always the same on the same machine.

The problem is - to go deeper to get to the manufacturer's ID the OP would either need an SDK from that manufacturer or develop a lower-level library that could do that. WMI goes as far as providing the IDs outlined in the post.
