Q: problems with Multiport AV adapter

Gang,

 

I just got the Multiport AV adapter and I cannot get any USB3 hard drives to work with it.

 

I have the simpler USBC->USB SS adapter from Apple and others and that works, but not the AV adapter.

 

 

 

I could get audio devices to work fine?

 

Also does anyone know what the deal is with the downstream USBC port? Is that only for power (i.e the USB3 and Video are stripped from the connector)?

 

Thanks,

Gordon

    Nelson,

    I will contact Apple, they will ask me to post a problem report on Radar and they will come up with a solution.

    Thanks,

    Gordon

    Hi Gordon,

    I have 2.33 - received it via an App Store update a couple of months ago.

    Reddog,

    Did you stuff work before you did the update? Mine is still at version 1.58. I am checking with my contacts at Apple about the problem.

    Thanks,

    Gordon

    No.  These intermittent problems started a couple of months after I started using the MB.  I had the MAVA setup from the start.  I can't remember exactly when the issues started.  Since it is intermittent, I did not pay much attention until this happened a couple of times.  I remember hoping the firmware update would fix the issues.

     

    Below the details for the MAVA

    USB-C Digital AV Multiport Adapter:

      Vendor ID: 0x05ac  (Apple Inc.)

      Version: 2.33

      Serial Number: DLC532301LBG2KQAV

      Speed: Up to 1.5 Mb/sec

      Manufacturer: Apple Inc.

      Location ID: 0x14120000 / 3

      Current Available (mA): 1000

      Extra Operating Current (mA): 0

    to Gordon and Reddog:

    I've been reading your conversations about the problems with the MacBook 12.

    This "issues" as Reddog calls it, shouldn't happen at all, the computer should recognize the USB 3.0 devices all the time, not just at random.

    What I have found most intriguing is the fact that after a restart or a NVRAM the USB 3.0 is recognized for a while, then it fails again, there has to be a reason for it, and in my mind the only people who can solve this are the developers at Apple.

    Gordon, don't use the upgrade, all you're going to have is more problems.

    Nelson.

    Nelson,

    Apple asked me to write this up and put it on radar. As I see it the problem happens randomly with Reddog coming out of sleep. This happens randomly with the 2.33 update and one or the other (monitor or drive) will not reappear after waking from sleep.

    Wouldn't you also say this is the same problem you are having. Or is it different?

    BTW what version of MacBook do you have and what monitor and other devices are on the USB chain attached to the MAVA?

    Thanks,

    Gordon

    Thanks Nelson - and also thanks to the others contributing.  It looks like we are getting some traction.

     

    I want to add an issue, which I think is related, but which has not been discussed yet.

    I think the MAVA is linked to Bluetooth issues as well. 

    1. Sometimes my Apple BT mouse will disconnect. Mostly when this happens it will reconnect by itself or I can reconnect by turning the mouse off and on again.
    2. But on occasion this escalates and I need to turn off BT on the MB and turn it on again to reestablish a connection to the mouse.
    3. Now sometimes this will escalate again, causing BT to stop reacting to any commands. When this happens, simply disconnecting my USB3 drive from the MAVA will unblock all the processes blocked previously and all is back to normal.  Except when I plug the drive in again, it is not recognised. 
      (This step leads me to believe there could be a connection between BT misbehaving & the MAVA.)
    4. I noticed that since several weeks (since the MAVA driver 2.33 update ???), BT does not detect the battery level of the mouse any longer.
    5. Yesterday during a mouse disconnect episode, nothing worked to fix it and even the System Preferences crashed.  During the goings on at one point I got a message that the SystemUIServer was unresponsive.  Eventually after a soft reboot would not work, I had to power down the whole system.

     

    This is the latest from Luxembourg.

    Gordon: the problems I have are related to the failure of any device using USB 3.0 to be recognized by the computer. If a restart or a NVRAM is done, then the devices are recognized for a certain period, variable, but eventually the failure returns again. All this began after I upgraded the Multiport AV adapter to version 2.33.

    I have a MacBook Retina 12 inch early 2015

    Processor 1.3 GHz Intel Core M

    Memory 8 GB 1600 MHz DDR3

    Graphics Intel HD Graphics 5300 1536 MB

    Working with El Capitan now with 10.11.6

    Thanks for your help

    Nelson,

    Do a pram or NVRAM reset should not really effect the USB bus. Ok I need 3 questions answered:

    a) Does the drive just go away? If so does the notice that your drive was removed with unmounting appear?

    b) When the drive is gone, does a reboot fix this or do you have to fool around with it some more?

    c) Is this self powered or bus powered drive? model?

     

    I am wondering if I need to update my MAVA to 2.33 to fully test this.... I have 5 other USBC hubs so I guess that will be ok till they fix it.

     

    Thanks,

    Gordon

    Gordon:

    a) The drive doesn't mount in the desktop, either a flash drive or an external drive. (USB 3.0)

    b) If a reboot is done, the drives will mount for a certain number of times, then the computer fails again to recognize them, until a new reboot is done

    c) self powered. The flash drives are SanDisk 32 GB 3.0 and Silicon Power Jewel 80 8 GB

       the external drive is a My Passport Ultra WD 1 TB 3.0

    Everything using USB 2.0 mounts every time without fail.

    Don't do the upgrade, it goes in your hard drive, not in the device (Multiport AV Adapter) or hubs.

    Thanks again, Nelson

    Nelson,

    Don't worry this update does not go in the drives. USB-C requires almost all devices have a microcontroller in them. This update changed the properties of the MAVA only. Think of it this way... how would an update know how to change every single drive type attached to them? it can't! Also I bet not both of the drives were plugged in at the time of the upgrade and you are still having trouble with both.

     

    Quick question are these drives thumb drives or SATA drives plugged into a controller?

    Also are you using a monitor on the video port of the MAVA?

     

    Thanks,
    Gordon

    Gordon:

    Thanks for the explanation, I'm not an expert in these matters.

    The two flash drives are thumb drives, the Passport  is an external drive

    No I'm not using a monitor plugged into the MAVA

    I work in my office with an iMac 5K 27 inch, side by side, NOT directly connected to the MacBook, but joined wireless though the same network

    I use the MacBook when I'm away from my work place.

    Nelson,

    No problem that is why there are a lot of people here who specialize in certain areas. Me I do hardware design, mostly audio related, but I have been doing USB since day 1.

     

    One question, are you powering the MAVA with your MacBook power supply or from the MacBook directly?

     

    Thanks,
    Gordon

    I have the MAVA plugged with the power supply

    I also have a USB-C to USB adapter and I have the same problems as with the MAVA

    Thanks,

    Nelson,

    I think your problem maybe OS related more so than MAVA or USB-C related. It appears as though your drive problem happens with any connection to the USB-C port. The standard Apple USB-C to USBA is just a cable, there are no smarts in it at all.

     

    I have been busy with other stuff but spent the last 2 days trying to reproduce the problem. I did a bunch of test with drives running at HS and SS (USB3) and no problems. Then I updated my MAVA to 2.33, put a USB analyzer on the buss and started a bunch of tests. Sleep short, Sleep hour, Sleep overnight and I could not get any of the drives I have to fail.

     

    I can't really open a case with Apple unless I can reproduce this here and send them some valid data.

     

    Thanks,

    Gordon
