Referring to segfault error. I’m suspecting that you run Quartus software as a user, which means jtagd will also run as a user. Therefore, you must edit permission for the usb_device.

jtagd is part of the Quartus tools and is a daemon that provides the interface between the Altera tool accessing the JTAG chain and the USB driver.

Refer to link on how to fix USB driver permissions
