USB Device Connect/Disconnect in Windows C

[cgopalg]

Hi,

I want my application in Windows to detect USB connect/disconnect of *my* USB mass storage device.

I could able to get the USB connect/disconnect event in my application of *any* USB mass storage device.

How can I find the connect/disconnect event correspond to *my* USB mass storage device.

Thanks,
Gopal

Take a look at my WinUSB application, esp. the FindDeviceUsingWmi and AddDeviceArrivedHandler routines.

Thanks, I could check  FindDeviceUsingWmi and AddDeviceArrivedHandler routines from your cs project.

I understand that I need to again search whether my device is connected or not.

Do you have examples based on vc++?

When you add a handler, the handler routine will run on attachment.

I don't have a c++ example. My older examples use WM_DEVICECHANGE messages instead of WMI/System.Management.

Thanks, I could find my device when it is connected or disconnected by using lParam of the callback API.
