I edited my text to fix a typo, and when I submitted it again it lost the <code></code> formatting. Seems like a bug in the message board system.

Ah, figured it out. Editing the message changed [code] to <code> which is not right. I fixed it.

OK, I *think* I have figured this out. It looks like the driver information for a device, in particular device.getDriverInterface(), is not valid until you have received a newProperty() notification for the property "DRIVER_INFO".

If in the body of that notification you ask for getDriverInterface(), you get back valid information and can determine what class of device this is.

It seems to me that the documentation should note that the various queries about the driver are invalid until this newProperty notification has happened.

Sorry I was traveling and just saw this. But you already figured it out. Basically DRIVER_INFO contains information about the driver interfaces. This is usually the most reliable way to identify the device types/subtypes are reported by INDI.
