The logging information of PcanView shows the messages in valid order, instead the log from candump which shows the answers before the request! Further, two answers are missing which leads to sending the disconnect message after a time out of 500ms. This event is reproducible on any access to USB devices e.g. a flash memory stick or a web cam.
