So
I've bought some USB-C "tester" from the usual sources. Claiming the description
it should be able to track/tap on PD messages ...
AFAICR
USB 2.0 500mA
USB 3.0 ~900mA
But there are some "crazy" USB chargers out there without max. mA limit
Also USB-C is more *dangerous* due max voltage of 20V and 5A with USB-PD
The dealer with big A has dropped all bad USB-C cables
The conductors are crucial, it's the copper aka cable thickness
Some kernel developer, CEC maintainer, has detected bad HDMI cables.
