I'm implementing a peripheral device and the corresponding device driver. As I get a rare behaviour on my device I would like to get the answer from it to a read/write request. Is there any possibility to get the the answer of an opb-device (wether it is error or retry) inside a device driver to handle it? best regards, Matthias
