But I have no idea which error codes are supposed to be returned and which should be translated. I can only assume the change is correct for wdm_flush, but I wonder why we translate errors there and not anywhere else? I still get the error: couldn't open the QmiDevice: Version info check failed: Version info check failed: Cannot write message: Unknown error 512 from wdm_write for example. Shouldn't that have caused as retry somewhere? Or is that a task for the application? As you now understand, I am probably not the right person to test these things. I don't know anything about IO error handling at all. I did read through the LDD3 once, but it's all starting to fade Bjørn -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
