Double DBT_DEVICEARRIVAL when connect CY7C68013A

It is normal ?

I try detect device connection

I used RegisterDeviceNotification and catch WM_DEVICECHANGE

When I connect device I have very strange situation.

I see:

1) CONNECT  ( wParam = DBT_DEVICEARRIVAL )

2) DISCONNECT  ( wParam = DBT_DEVICEREMOVECOMPLETE )

3) CONNECT ( wParam = DBT_DEVICEARRIVAL )

It is normal ?

If i try other USB device (not cypress) for example USB memory 8GB all works OK 

I see one connect when plug in my memory.
