Use ftx_prog to allow max USB power consumption of 500mA
and change product/manufacturer name of FT231X chip:
ftx_prog --max-bus-power 500 To program ULX3S bitstream, there are many programming options:
ftx_prog --manufacturer "FER-RADIONA-EMARD"
ftx_prog --product "ULX3S FPGA 12K v3.0.3"
ftx_prog --new-serial-number 120001
ftx_prog --cbus 2 TxRxLED
ftx_prog --cbus 3 SLEEP
Optionally you can change "45K" to "25K" or "12K" in regard with FPGA chip size.
Re-plug the USB and it will appear as new name which can be autodetected
with USB-serial JTAG tool.

# Programming over USB port "US1"
Factory default (empty) onboard FT231X has to be initialized in order
to be autodetected by "ujprog" or "FleaFPGA-JTAG" use ftx_prog.
This needs to be done only once and board will remember it
after power down. Settings enable max USB power consumption of 500mA
set autodetectable product/manufacturer name of FT231X chip, serial
number, set proper USB-serial activity LED and sets CBUS line to
wake up board when FT231X is enumerated by host computer (PC).

If running linux, some udev rule is practical in order to allow non-root users
(in given example, members of "dialout" group) access to the USB-serial JTAG:
# file: /etc/udev/rules.d/80-fpga-ulx3s.rules
# this is for usb-serial tty device
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", \
MODE="664", GROUP="dialout"
# this is for ujprog libusb access
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", \
GROUP="dialout", MODE="666"
"ujprog" tool acceps BIT or SVF files for uploading to the FPGA SRAM. "ujprog" tool acceps BIT or SVF files for uploading to the FPGA SRAM.
