Or install it directly:

gem install usb-ruby

Usage

require "usb"

USB::Context.open do |context|
  context.devices.each do |device|
    descriptor = device.device_descriptor
    puts format("%03d/%03d %04x:%04x",
                device.bus_number,
                device.device_address,
                descriptor.vendor_id,
                descriptor.product_id)
  end
end
