No driver installation is necessary to use the Pololu USB AVR Programmer or Orangutan SVP in Linux.
When you plug your programmer or Orangutan SVP into a Linux computer, the Linux kernel’s cdc_acm driver should automatically detect it and create two or three serial port devices. Unless you have other devices plugged in that use the same driver, the name of the programming port should be /dev/ttyACM0. You can see what virtual COM ports you have available by typing
ls /dev/ttyACM* in a terminal.
