notes for using the ULX3S
Maybe linux ujprog won't find port because of insufficient priviledge. Either run ujprog as root or have udev rule:# 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"
