If you're a follower of this and my other collections, you'll recognize the Twinkie analyzer tool : https://www.chromium.org/chromium-os/twinkie
Up until recently, the tool has been slightly clunky to use. Getting to Twinkie's command line required a Linux distro running on a PC, and even then, the specific instructions included installing the "usbserial" driver and writing Twinkie's USB VID:PID into sysfs to tell the usbserial driver what Twinkie is.
Recent Linux kernels have changed that because Google's serial devices (of which Twinkie is one) have now been included in the usb_serial_simple driver, so it should just be plug-and-play for recent Linux distributions.
As of Chrome OS 55, the necessary kernel patches are now in live in stable channel on Chrome OS as well.
What does this mean? If you're a Chromebook user and a Type-C enthusiast or developer, it's now possible to use Twinkie's command line interface without being in Developer mode, and without using Crouton or anything else.
Instead, install BeagleTerm : https://chrome.google.com/webstore/detail/beagle-term/gkdofhllgfohlddimiiildbgoggdpoea?hl=en
Then plug in Twinkie, and launch BeagleTerm. All works while the Chromebook is even in Normal mode (secure boot).
This will also work with +Plugable
's USBC-TKEY version of Twinkie available here : http://plugable.com/products/usbc-tkey/
