OnDeviceChange Events

[harleydude]

I have noticed the following in the logger since upgrading to G5, at least I dont recall seeing them in G4. What do they mean? Is there a list of the codes somewhere?

I know that this is an old thread, but I've just run into this myself :

more info is here :

7 = DBT_DEVNODES_CHANGED (http://msdn2.microsoft.com/en-us/library/aa363211.aspx), A device has been added to or removed from the system.

there is no additional info, on which device has been added...

in my case, I see this event, if I power on/off my TV !

the TV is connected via HDMI, to the G5 PC (vista ultimate).

and, for some reason, powering on/off the TV, causes problems with one of my G5 controlled USB devices (VFD display shows bad data) so I need to reinitialize it after above event occurs...

I don't know, if it's a vista problem, an interrupt sharing issue between the nvidia PCIe16 graphics card and the USB controller, just sensitive timing in the VFD display firmware or something else..
