    I'm looking into getting a new monitor, possibly a 4K monitor, but likely just a 2560 x 1440 (WQHD) model. I like the specs of the new Dells (2715Q, 2715H, 2515H), but am particularly interested in the built-in USB 3.0 hubs, as I plan to use the monitor with a 2013 15" rMBP in clamshell mode. The newer Dells all appear to have same 1-up/5-down USB 3.0 hub, with one of the hubs having high-output (I'm assuming 2.1) charging capabilities.

    Can anyone with personal experience comment on how well the built-in USB 3.0 hubs work? One question I had is whether the four non-"high power" USB ports on the hub are still powered - i.e., could they power a bus-powered USB 3.0 external HD?

    Many thanks in advance.

    I have been using the Dell U2715H for a few weeks now and have been running my iTunes and photo library off of a USB 3.0 SSD drive flawlessly connected to the monitor. I've also have my time machine backup drive connected as well and can charge my iPhone/iPad with no issue. A really great monitor in my opinion. Here is a screenshot of the USB 3 speeds on the SSD.

    Thank you! Glad to hear that this has been working well. I'm assuming based on your description that all the USB 3.0 ports on the monitor are powered (and not the just the "high-powered" one). Is that correct?

    Correct. The "high powered" port is the one on the back. Here is a snippet of the manual:

    Hi,

    I just got a Dell U2414H UltraSharp monitor with the USB 3.0 hub. The monitor looks great but I haven't been able to get the USB hub to work. I have it connected to a 2012 15" Macbook Pro which is USB 3.

    When I connect it I get a notification;

    "USB Devices disabled. Unplug the USB device using too much power to re-enable USB devices"

    I've tried plugging in multiple USB devices (hard drive/stick/mouse/keyboard) but nothing works. The light on my mouse illuminated but no signal connection.

    The mac boots in to Windows 7 as well and it is the same problem.


    I got in touch with Dell about it and first they tried updating the drivers and then they very quickly sent out another monitor (with hand prints all over the screen) but it did exactly the same thing. I've just been on the phone with them again and they insisted the monitor is fine and that I have to get in touch with Apple because Dell don't support them.

    Both the original and the replacement monitor are Revision A01.


    @DFWHD

    Would you mind telling me which Revision monitor you have? I read a few posts on the Dell forum about the USB 3.0 hub not working on earlier revisions.

    ...dumb question? Is it?

    It's printed on the back of the monitor, on the same label as the Serial No. and the Service Tag. It will read something like;

    "Rev A01"

    I hope you didn't think I was saying your question was dumb, I meant that I felt dumb for having to ask... Mine has REV 00 on the back and the USB hub is still functioning fine.

    You know, I did wonder, but I lived in the States for a year and I know how our English differs so I was sure you weren't talking about me...ha ha

    Well, I ordered another USB 3.0 A - B cable and it turned up today and it's improved the situation. Not every USB stick is working but most are.

    Thanks for checking the Rev. I'm glad it's working better, it's a really nice display.
