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"
