This error message may appear during device operation, or upon connecting your Logic device. This error appears when the Logic app detects that a device gets physically disconnected from the PC during initialization. This could be due to a bad USB connection, a faulty USB host controller driver, a fauly Logic pod, or other unkown reasons which might cause the USB connection to time-out during initialization.
2. Test your Logic hardware on another PC.
3. Test your Logic hardware using other USB ports, and connect directly to the PC's USB port without any extension cables or USB hubs in between.
4. Test your Logic hardware using another USB cable.
5. Try removing all other USB devices from your PC before connecting Logic.
6. Try manually installing the Saleae drivers via the instructions in the below support article.
7. In some cases, this issue can be resolved by uninstalling the USB 3 host controller driver, and allowing Windows to automatically re-install the same driver during a reboot. Specifically, this may solve the problem for users with the Intel USB 3.1 eXtensible Host Controller, like the one shown in the image below. If you have an Intel based USB 3 host controller, first navigate to the USB host controller driver from Device Manager and double click it to open the properties window, (be sure it's the Intel eXtensible Host Controller) then uninstall the driver by clicking "Uninstall Device" under the Driver tab in the device properties, and restart the PC. Once restarted, Windows will automatically re-install the same driver, and in many cases, this resolved the connectivity issue with our devices.
