A.2. Troubleshooting Procedure for Error when scanning hardware - No Devices

You might see this error when connecting multiple download cables to your computer and executing jtagconfig command.
Error when scanning hardware - No devices

It takes a certain finite amount of time for your computer to finish the USB device enumeration after connecting USB devices. The more USB devices are connected, the more time is required for the USB device enumeration.

The above error occurs when jtagconfig command is executed before your computer finishes the USB device enumeration to recognize all download cables connected. The error seems to occur only when jtagconfig command is executed right after multiple download cables are connected

Troubleshooting Procedure

You need to wait for a while until your computer finishes the USB device enumeration after your Intel® FPGA Download Cable is connected. You can use Device Manager on Windows or lsusb command on Linux to check if your Intel® FPGA Download Cable is recognized on your computer.

For Windows: Open Device Manager and check if Intel® FPGA Download Cable II (JTAG interface) under JTAG cables or Intel® FPGA Download Cable under Universal Serial Bus controller is listed.

For Linux: Open a command shell, type lsusb, and check if the device with ID of 09fb:6001, 09fb:6002, 09fb:6003, 09fb:6010, or 09fb:6810 is listed.
