UD-CA1 & Late 2016 13" MacBook Pro Charging

Just received by UD-CA1 and was very excited to try it out. Unfortunately my laptop does not respond to the unit very well. It keeps cycling from charging and battery although under system report I see the unit is providing 60W of power. Any idea what is causing the unit to operate incorrectly?

I have a late 2016 13" MacBook Pro with Touch Bar.

  • Hi Daniel,

    We replied via email to your direct inquiry, but are posting it here as well just in case the email didn't make it through. Thanks!

    ----------------

    Sorry to hear about the issues here -- certainly sounds like something in the dock isn't working as it should.

    I think the best approach will be to have a replacement unit pre-tested in our labs and sent to you. Since you've already provided the Order and Serial numbers (thanks!) I'll just need your preferred shipping address to get this arranged.

    Thanks,
    Gary

  • I have this exact senario on mine. Just received the dock yesterday, brand new Macbook Pro late 2016 13", worked great for about 5 hours then started switching between charging and battery, happens now every 10 seconds or so, basically disconnecting and reconnecting the dock constant and laptop going from power to battery and back.

  • Did you try using the cable that came with your MacBook's charger? I purchased a separate apple charger and cable, the second "official" apple cable I purchased seems to work better. No charging drop outs now. That said, I still can't figure out why the ethernet fails to connect.

  • I will try using the mac one and see thanks for the advice. I wish I could help with the ethernet, but my ethernet works great.

    • So interesting results, the USB-c cable that came with my mac for the charger doesn't pass any data, it charges my mac fine from the dock, but there is no video or USB working, seems that cable is a one way power only usb-c cable. The separate charger and cable you purchased maybe is a proper full featured cable. I also had a third party USB-C charger with a cable and it also will not pass data. For now dock seems fine if I also plug the mac into power directly in another USB-C port, so seems the dock is not providing enough power or something.
    • Well when I used the new cable power seems to be fine and I can connect a couple different USB devices to the hub and they work. Ethernet still dead, recognizes it but never connects. I'm wondering if I have a driver issue or something ... Just a side note when I compare the thickness between the cables I can see a slight difference between the two official apple charging cables. I believe you are correct about the cable not being a true usb-c 3.1 or Thunderbolt 3. Frustrating that apple would sell a cable for as much as they do and it's not a full featured 3.1 cable or Thunderbolt 3 cable.

  • Rob and Daniel,

    Appreciate the additional details here! This is good info to help understand what's going on when this behavior occurs.

    Rob, can you please email support@plugable.com so we can get a few order details and arrange a replacement?

    Daniel, did you have any luck with the updated ethernet driver we sent over via email? (If it didn't make it through, please let me know and I'll re-send.)

    Thanks!

  • The email did come through I just didn't see it in my inbox. Will try it out later this afternoon.

  • Ethernet is still not working. I actually decided to wipe my MacBook and reinstall my system this evening. The first thing I did after starting with a clean install was to install the new driver you sent. Unfortunately the ethernet adapter shows up but never shows a connection.

    Here is something that might be helpful in troubleshooting. The green status light flashes with what I assume is a valid network activity ... until I plug the docking station into my MacBook. After that the green light turns off and the orange stays solid.

  • Out of curiosity I used a StarTech 0.5m ThunderBolt 3 cable I had purchased for my Samsung T3 SSD. Now the ethernet works and charging seems to be stable. Why didn't the included cable work? I'm guessing the apple USB-C cable that I purchased could carry enough current, but couldn't handle the data? ... Disappointed. The StarTech cable works but I really need one > 6' so I can place the dock under my desk and connect via one cable to everything.

    Do you have a list of cables that will work with this dock that supports both the power requirements (60W) and correct USB-C standard?

  • I’m not happy....
    Today is January 3rd, 2017.
    Received plugable UD-CA1 on 12-30-2016 but didn't take it out of the box until today.
    No displays, network, or peripherals connected to UD-CA1.
    Just power from wall to UD-CA1 and then USB-C cable that came from plugable to Late 2016 MacBook Pro 15" with touch bar.
    At first Mac was charging. Then it started "dinging" every 7-10 seconds and the screen on the laptop dims. The laptop charges, then disconnects, lather rinse repeat.

    I tried disconnecting the UD-CA1 from the laptop, waiting a few seconds and then reconnecting, same results.

    I tried using a different USB-C port on the laptop, same results.

    I then tried using the Apple USB-C cable. That worked, but I don't want to have to keep reaching around behind my monitors to get my charging cable to take home every day. That is why I bought a docking station. Also, the Mac USB-C cable that came with the laptop/charger doesn't seem to do data. When I connect a USB peripheral to the UD-CA1 while the MAC is connected to the UD-CA1 via the Apple USB-C cable, then USB peripheral is not detected. However, same USB peripheral connected to a USB-A USB-C dongle does work.

  • I sent mine back and got a second one and the second one has run flawlessly so far for 3 full days (first one worked for 5 hours before getting the disconnect reconnect issue). I have it on a 13" macbook pro with touchbar brand new 3 weeks ago and the dock is pretty loaded up, using hdmi, 4 USB devices including external HD and ethernet. Seems it is just poor QC or the mac to dock usb-c is poor quality and is easily damaged or hit or miss.

  • @Ben Russo,

    Appreciate the details Ben. In our continued testing, it seems like there's some potential interference in play here with the high-frequency signaling. We're only hearing reports of this from some MBP Touchbar owners. (Non-touch models don't seem to exhibit this behavior as best we can tell at this point.)

    The Apple cable will support power/charging, but not video -- but regardless, certainly understand your desire for things to work through a single cable as intended.

    A couple things to suggest:
    1) Can you please confirm you've installed the 10.12.2 Sierra update through the App Store?

    2) Can you please try disconnecting from Wi-fi and seeing if that helps?

    Thanks!
    • @Gary Z,

      Thanks for the reply.
      I confirmed that I am running the 10.12.2 Sierra update.
      I disabled WiFi, and I am still getting the charging / not-charging (repeat) continuously. (Note: this is with the plugable UD-CA1 included USB-C cable. again, if I use the Apple cable then charging works continuously, but no docking station function other than power.)

  • @Ben

    Thanks for confirming the update and the behavior with wi-fi disabled. Can you please email support@plugable.com so we can arrange to send you a replacement cable to see if that helps? (We've had good luck with this approach on the few we've sent out thus far.)

    @Lorenzo

    It looks like you worked with Josh via email and a replacement cable is on the way. Look forward to an update after you've received it and had a chance to test.

    Thanks!
    • @Gary Z

      Thanks, I will contact support@plugable.com.
      I did try the UD-CA1's included USB-C cable with the Apple-Charger/Laptop.
      That worked just fine. Very simplist testing, I know....
    • Thanks Ben! Looks like Josh has a cable on the way to you after you emailed in, so looking forward to hearing how it goes.

      Also, appreciate the note about successfully using the provided cable with the Apple charger. When we're seeing the interference, it seems to happen in scenarios where power and video/USB data are being sent over the same cable. In scenarios where just power or data or video are being carried, all seems to be well. So we appreciate the additional testing data that seems to align with what our findings.

  • So, had great luck with my second dock, used it for nearly a month without issue. Ordered 2 more as we would like to use this as our company docking station for the new mac's as it is the best design out there. The first of the 2 new ones worked for about 7 hours and then started having the power on off issue charging the mac. Decided to play switch around with the 2nd doc changing out one thing at a time and no combination of cables would make it work again. Switched the dock out to the other new one with all the cables it came with and it has the power issues immediately. I will email support and try another cable to troubleshoot, current running an apple adapter also plugged into laptop and all works fine with the extra juice.

  • I have had the same problem come up. If I turn the Macbook Pro off and let it charge. Once it's charged up, it works like a charm. I haven't tried swapping the cables yet.
