Worth noting that the issue doesn't always happen. For instance the test did pass for next-20240110 and then failed again on today's next [3]. But it do= es seem that the issue was introduced, or at least became much more likely, be= tween next-20231221 and next-20240103, given that it never happened out of 10 runs before, and after that has happened 5 out of 7 times. Note: On the Tomato Chromebook specifically this USB controller is not conn= ected to anything.
