Re: [Libusb-win32-devel] libusb-win32 plug events

[Stephan M. <ste...@we...>]

Have a look this source code:

http://libusb-win32.cvs.sourceforge.net/libusb-win32/libusb/src/service/service_nt.c?hideattic=0&revision=1.5&view=markup

This is the source of a service that was part of older versions of
libusb-win32. It does what you need.

Basically, you have to do the following:

* use RegisterDeviceNotification() to activate device notification events
* listen to SERVICE_CONTROL_DEVICEEVENT (service) or WM_DEVICE_CHANGE
  (normal app)  events
* use libusb to rescan the whole bus for new devices
* open new devices
