Hi,

Currently how I do this is I poll for a masked list of USB devices (masked specifically for the device I'm working with) and if it's there, I continue, if not then I notify the user that the device is not connected. The method for getting a list of USB devices is provided for me through a USB peripheral controller chip manufacturer's .NET library.

Is there an event somewhere for a USB device disconnect?

have you checked out the Win32_USBControllerDevice class? http://msdn.microsoft.com/en-us/library/aa394505(VS.85).aspx

I should clarify; I'm actually using a USB peripheral controller chip (big difference, should've worded that better)I'll look into that class, thanks Jose.Also, I did find this too: http://msdn.microsoft.com/en-us/library/aa363480(VS.85).aspx WM_DEVICECHANGE
