Description

Description of files:

  • blinkstick.rb - main BlinkStick class definition
  • example-info.rb - displays information of each BlinkStick
  • example-infoblock.rb - read/write info block sample
  • example-off.rb - turn all blinksticks off
  • example-random.rb - set random color to all blinksticks

Running examples:

ruby example-info.py

Permission problems

If the script returns with an error

LIBUSB::ERROR_ACCESS in libusb_open

You can either run the script with sudo, for example:

sudo ruby example-info.rb

Or you can add a udev rule to allow any user to access the device without root permissions with this single command:

echo "SUBSYSTEM==\"usb\", ATTR{idVendor}==\"20a0\", ATTR{idProduct}==\"41e5\", MODE:=\"0666\"" | sudo tee /etc/udev/rules.d/85-blinkstick.rules

Reboot computer after you have added the command and all users will have permissions to access the device without the need of root permissions.
