I am trying to wite a service that will detect when a USB storage device is
inserted to display a warning message. I have written the service that
detects USB device insertions but I get my message when any USB device is
inserted. I would like to narrow that down to just storage devices, thumb
drives and external hard disks...

Can someone point me in the correct direction as to how I can narrow that
down ?

Thanks,

When you register for hardware change notification, maybe you specify a
wrong id in the filter.
You need DBT_DEVTYP_VOLUME, or DBT_DEVTYP_DEVICEINTERFACE
with class = DiskDrive or Volume.

//Add these code to the initialization part

DEV_BROADCAST_HDR NotificationFilter;
NotificationFilter.dbch_size = sizeof(DEV_BROADCAST_HDR);
NotificationFilter.dbch_devicetype = DBT_DEVTYP_VOLUME;

hDevNotify = RegisterDeviceNotification(hMainWnd, &NotificationFilter,
DEVICE_NOTIFY_WINDOW_HANDLE);

///<\Custom Initialization Code>

//Application_Run(), can also be a message loop.

UnregisterDeviceNotification(hDevNotify);

//So that you can get notifications only when Mass Storage Device is
inserted.

I tried your example and I get a 0x42A returned from
RegisterDeviceNotification(), any idea ?

I did figure out the 42a was because you cannot register for a broadcast
volume. I do receive the broadcast volume on thumb drives but do not receive
anything for CD/DVD media insertion. Is ther some other method to receive the
change for media on cd/dvd devices ?
