Hi all,

I've embarked on a exploratory mission on the device access part for OSGi 4 with the goal of maybe getting a small/simple prototype up and running for
talking to devices over USB.

I've read through the specification but I'm just not able to wrap my head around this thing and get a clear picture of how it is supposed to work... I'm waiting for the "OSGi in action" book but in the meantime, does anybody
know of a "HelloWorld" or similar?

Thanks

Hi Patrik,

I don't know of a HelloWorld example that exists out there, but I've recently donated an implementation of the device access spec to Apache Felix. I can cook up an example for you, if you want.

What you probably need is some kind base driver that is able to detect (in a low-level way) that a device has appeared on the USB bus. Based on the limited information that has then become available about the device a Device (in the sense of the device access spec) must then be registered within the framework. It is then up to the device manager to locate possible drivers that match the detected device.

Regards, Dennis
