You can probably use WMI classes.
Win32_DeviceChangeEvent triggers when devices are added or removed.
You could probably key off that event to check to see if the device you wanted exists


Tie it in with PnPDevice:

 try
            {
                ManagementObjectSearcher searcher = 
                    new ManagementObjectSearcher("root\\CIMV2", 
                    "SELECT * FROM Win32_PnPEntity"); 
 
                foreach (ManagementObject queryObj in searcher.Get())
                {
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Win32_PnPEntity instance");
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Caption: {0}", queryObj["Caption"]);
                    Console.WriteLine("ClassGuid: {0}", queryObj["ClassGuid"]);
                    Console.WriteLine("Description: {0}", queryObj["Description"]);
                    Console.WriteLine("DeviceID: {0}", queryObj["DeviceID"]);
                    Console.WriteLine("Name: {0}", queryObj["Name"]);
                    Console.WriteLine("PNPDeviceID: {0}", queryObj["PNPDeviceID"]);
                    Console.WriteLine("Service: {0}", queryObj["Service"]);
                    Console.WriteLine("Status: {0}", queryObj["Status"]);
                }
            }
            catch (ManagementException e)
            {
                MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
            }

Plater,
Do you have the whole windows service project that detect usb?

[Dheeraj Joshi]

Use WMI to achieve this.

This link may help WMI and USB

I used the code that in the link above.
but it doesn't work.
do someone have widows service project that detect USD devic?
( or at least code that works well)

[Dheeraj Joshi]

The link was to give an idea. You need to write your own code(I did not tried to execute the code in that link. But i wrote my own code which detected USB connection/Disconnections).

Can you bring me the cide you wrote?

[Dheeraj Joshi]

You can also use Temporary or permanent even consumers to do this job.

[racheli10]

Can you give me an idea?
I am new programer. and i nedd it very necessary.
thanx

[Plater]

Best advice to give a new programmer:
Start reading up APIs and function calls and working things out for yourself. Give it a try.

If someone anyway can bring me project it will be very good.
I need this ASAP
