To: linux-usb-users@lists.sourceforge.net Cc: linux-kernel@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello listees, we are struggling with a 3rd party USB device. It comes with its own firmware and its own Linux USB serial drivers. Unfortunately the communication between the device and the user application seems to break down from time to time. This situation can easily be resolved by unplugging and then re-plugging the device. Unfortunately this requires manual intervention. While resolving the real issue would be the preferred way to deal with this problem, we would settle for a way to do a software unplug/re-plug. Can this be done at all? If so, is there a tool to do this? A detailed description of our environment: * Linux 2.4.21 with USB OHCI driver * Natsemi Geode integrated CPU/Chipset Thanks in advance Joerg Mit schönen Grüßen von Yahoo! Mail - http://mail.yahoo.de
