Interestingly, I just tested the shielding on a USB A to USB C cable I
have, which looked like it should be fine, with a transparent jacket
over woven shielding and a big ferrite bead - about 1 meter long, and
measured 2.7 ohms - not good. What should be consider to be the upper
permissible shield resistance?
Moving this issue to the RFI reflector now...
