Here a really cool hint, when you are searching for the best USB Blaster on the market, to program your Intel FPGA. I switched the mode back to JTAG, and it still finds the device and I can program it. I opened the Quartus programmer, and changed the mode from JTAG to Active serial programming, and the device shows up. I thought it might be an EPT issue but it wasn't. usb 3-11.2: FTDI USB Serial Device converter now attached to ttyUSB0 ftdi_sio 3-11.2:1.0: FTDI USB Serial Device converter detected usbserial: USB Serial support registered for FTDI USB Serial Device usbcore: registered new interface driver ftdi_sio usbserial: USB Serial support registered for generic usbcore: registered new interface driver usbserial_generic usbcore: registered new interface driver usbserial usb 3-11.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 3-11.2: New USB device found, idVendor=0403, idProduct=6001 usb 3-11.2: new full-speed USB device number 31 using xhci_hcd usb 3-11.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0
