add udev rule

sudo vim /etc/udev/rules.d/99-USBasp.rules

add the following

# USBasp - USB programmer for Atmel AVR controllers
# Copy this file to /etc/udev/rules.d so

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", SYSFS{idVendor}=="16c0", SYSFS{idProduct}=="05dc", MODE="0666", GROUP="dialout"

reload

udevadm control --reload

solder header pin on JP2 and connect the two of them

connect the first usbasp to the second usbasp

update firmware

cd usbasp
