ls /dev/tty* not enumerating USB devices about pixelbook-linux

I presume you are still in Chrome OS. Did you try flipping the usb-c end the other way around? Apparently the suziq is not symmetrical

Can someone help clarify on how to install this rule; I believe this to be what is causing the USB failing to enumerate in /dev/tty:

There is a udev rules file, extra/usb_serial/51-google-serial.rules that should be installed in /etc/udev/rules.d/ and udev should be told to reread its rules. This rules file can be installed using the extra/usb_serial/install script.

after reading thru this:
https://chromium.googlesource.com/chromiumos/platform/ec/+show/master/docs/case_closed_debugging.md
udev files must be installed incorrectly or need to be reread ?

issue resolved.

Linux (beta) files needed to be installed via settings before CR50 cable was recognised and enumerated in CROSH shell.
