Is there a simple test that someone could do with a multimeter to test these cables themselves? Or is it more than just having a pullup resistor on the right pi

- proee 11y agoThese are very high-speed cables, so there's a lot that can go wrong from a signal integrity standpoint.
- acqq 11y agoI've got an impression that he just checks if they are good for charging?
- Johnny555 11y agoI can't even remember the last time I used a USB cable on my phone for data, the only time I ever plug it in is for charging, so I don't care too much about signal integrity as long as it will charge my phone without damaging it. When I do care about signal integrity (i.e. connecting a USB hard drive to my computer, I use name-brand cables)
- acqq 11y agoHis reviews that I've read up to now do seem to be about if the resistor exists at all (if it doesn't the devices don't draw more current) or if it's of false resistance (and then the devices can try to draw more than the power source can provide, potentially damaging it).

- smackfu 11y agoInteresting that the Pixel can tell it's a bad cable. Makes me wonder if it will still charge from it.
