Detecting USB HID insertion and removal

[nnsimon]

Hey All

I am a newib to nrCommLib.  I have been looking at the examples and i am a bit lost.  What i want to do is

1. Detect the insertion of a usb HID device
2. Check the name/serial number of the device that was inserted
3. Detect the removal of the device

It is important that the sequence occur in the above order.  I have been able to detect the device but only if it is already inserted. The device may not be removed or inserted at any time.

Which component(s) do i use? How would i use it/them?

Thanks in advance for any help

Hello

Please take a look HID Demo:

{nrCommLib}\Demos\HidDemo\hiddemo.dpr

It detects WM_DEVICECHANGE and updates device list.
You can compare the device list before and after receiving this message.
