I don't have any problems with any cables - as long as they are plugged in completely.
I bought a bunch of cables on the jungle river site, several different lengths. They work great, but on some of them the metal connector at each end is not out of the plastic far enough so they only have about 1mm of contact. Move it even a little and the connection is lost.
Cutting the plastic shroud helps expose more of the plug itself.
