How to solve "No Lattice cable detected on any port" and no detect cable on the GUI in newly installed Ubuntu 20.04.3?

•  sudo apt-get install libxcb-input0


• sudo apt-get install libxcb-xinerama0

Note: at default the install path = /home/<username>/lscc/radiant/3.0/programmer/bin/lin64

4.A.  If libusb.so.1 error occurs, use the following command:

•  sudo apt-get install libusb-0.1.4

Step 1: Giving HW-USBN-2B (FTDI) USB Drivers Read/Write Permission to Selected Individuals

1.       Plug in the USB cable.

2.       In the terminal, type:

lsusb

You should see an entry similar to the following:

> Bus 001 Device 002: ID 0403:6010 for Lattice HW-USBN-2B (FTDI) USB Download Cable

3.       This mean the FTDI chip is in Bus 001 and device 002. Go to the directory of the bus number

cd /dev/bus/usb/001

4.       Grant execute permissions to the device number. On the command line, type:

sudo chmod 755 002

 Note: If the specific grant permissions command is not working to your linux system try sudo chmod 777 <device#>. Example: sudo chmod 777 002.

5.       Unload the ftdi_sio driver if it is attached to your device.

sudo /sbin/rmmod ftdi_sio

6.       Unload the usbserial driver if it is attached to your device.

sudo /sbin/rmmod usbserial

Step 2: Driver Setup

Automated UDEV Method Configuration

1. Create an entry called \u201Cplugdev\u201D in the /etc/group file, and then add

a.       Make sure /usr/bin/id shows you as a member of the plugdev group. Log out if required.

b.       Make sure to save the group file after editing (you need to be root to edit the file)

Example:

plugdev:x:501:lmnapps

2. Type the following command to execute the script:

sudo <install_path>/data/vmdata/udevsetup_ubuntu

Example:

sudo /home/lscc/radiant/3.0/data/vmdata/udevsetup_ubuntu


5. Now try to open the programmer.
