Where's the eMarker chip in a USB cable? And what does it do?

    5:28 - regarding the shield. Obviously the destructive test of cutting open the cable can show whether the shield is in place.
    But perhaps there is some way to use an interference signal outside of the cable to see if that interference is attenuated within the cable?

      Good point, but I have to pay for the cables myself :D

      @ - that’s why I suggested to see if external interference is attenuated by the shield. I think destructive tests should be the last resort.

    You forgot to lookup up the vendor name using the vendor ID.

    just because theres parts, doesnt mean they do anything..... the fact they can be seen under a nice clear cover to me suggests they are not functional but just bling

      The tool shown in the video is reading data from the eMarker chip. That data can't come from anywhere else, if there was no chip present.

    Do you have a special reason to wear those gloves in your videos ?

    USB-C is the most stupid thing ever. Cables which look the same behave differently. Bad Idea!!

      would you rather have a house fire by running 240 Watts through some low grade cable. e-marker is a safety feature so devices dont push more power than the manufacturer rated the cable for.

      I use them for three different things in my house, you would rather I had to keep three different kinds of cables? Yeah only one of my cables supports DisplayPort... but 99% of the time I can just grab whatever cable is convenient and it will work at least to some extent for charging and data.

      So you want to switch the physical plug whenever another feature is added? Bad idea..

      The same happened on USB-A. Would you rather have a different connector every time any spec changes?
      The idea is solid, especially as it provides great downward compatibitily. The issue is a lack of transparency and a certain complexity, which may confuse casual users.
