You can probably use WMI classes.
Win32_DeviceCha ngeEvent 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:
[code=c#]
try
{
ManagementObjec tSearcher searcher =
new ManagementObjec tSearcher("root \\CIMV2",
"SELECT * FROM Win32_PnPEntity ");

foreach (ManagementObje ct queryObj in searcher.Get())
{
Console.WriteLi ne("-----------------------------------");
Console.WriteLi ne("Win32_PnPEn tity instance");
Console.WriteLi ne("-----------------------------------");
Console.WriteLi ne("Caption: {0}", queryObj["Caption"]);
Console.WriteLi ne("ClassGuid: {0}", queryObj["ClassGuid"]);
Console.WriteLi ne("Description : {0}", queryObj["Descriptio n"]);
Console.WriteLi ne("DeviceID: {0}", queryObj["DeviceID"]);
Console.WriteLi ne("Name: {0}", queryObj["Name"]);
Console.WriteLi ne("PNPDeviceID : {0}", queryObj["PNPDeviceI D"]);
Console.WriteLi ne("Service: {0}", queryObj["Service"]);
Console.WriteLi ne("Status: {0}", queryObj["Status"]);
}
}
catch (ManagementExce ption e)
{
MessageBox.Show ("An error occurred while querying for WMI data: " + e.Message);
}
[/code]

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) .

[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
