I received today your USB Type C Cable,JSAUX (2-Pack 6.6FT) USB 3.0 to USB C Cable Fast Charger Nylon Braided Cord for my Samsung Galaxy Note 8 . I used one of the cables on 3.0 port and it charged nicely. Subsequent to that. I found a small instruction card in the envelope that contained the cables. My question: why, on that card is there an X through the "Computer USB Port"? It gave me the impression that you only want this cable used with the "Original wall charger of your phone," which, as you know, is the wording beneath the green check-marked illustration next to the X-ed out Computer USB Port illustration.
