On a Raspberry Pi the device shows up as /dev/ttyACM0.
Install package kmod-usb-acm first
After installing, you will get some log like
[47056.710000] usb 1-1: new full-speed USB device number 4 using ehci-platform [47056.940000] cdc_acm 1-1:1.0: This device cannot do calls on its own. It is not a modem. [47056.950000] cdc_acm 1-1:1.0: ttyACM0: USB ACM device
# ls /dev/tty* /dev/tty /dev/ttyACM0 /dev/ttyATH0 /dev/ttyS0
After that it's just a cat /dev/ttyACM0 to read the output.
