AUKEY has started to sell its latest USB Type-C hub for Apple’s MacBook laptops and other computers that need something more than USB-C and wireless interconnection technologies. The new CB-C55 hub expands the port allocation to provide outputs for displays, projectors, Gigabit Ethernet and traditional USB Type-A devices, along with supporting power delivery input to the main machine.

Modern notebooks are very thin, whereas legacy ports like 8P8C/RJ45 (Ethernet) and D-Sub were designed in the seventies and the eighties when PCs only existed in desktop form-factors. Even more modern ports such as the HDMI port were not designed for ultra-thin laptops. Today, it is either impossible or very complicated to install such ports into ultra-thin notebooks, and the opinion of some OEMs is to combine them into a single USB-C port and require additional dongles. As a result, various dock stations and USB Type-C hubs are gaining popularity because people still need their legacy devices/connections, but want to have the thinnest and lightest devices possible.

The AUKEY CB-C55 USB Type-C hub was designed primarily for road warriors who use modern ultra-thin devices such as Apple’s MacBook, MacBook Pro (2017), HP’s Spectre, Lenovo’s Yoga 900, Google’s Pixel and others. The CB-C55 has a two USB Type-A connectors, a D-Sub header (max resolution is 1920×1080), an HDMI output (max resolution is 3840×2160 at 30 Hz) as well as a GbE port. The unit is made of matte aluminum and weighs 120 grams.

Like many other USB hubs from AUKEY, the CB-C55 has its own power connector and thus can power laptops as well as devices that can be charged using USB ports. The input of the CB-C55 is 5-12 V at 2 A, so, the maximum amount of power it can deliver is about 24 W. Meanwhile, since the CB-C55 only supports USB 3.0 Type-C interconnection, the maximum bandwidth it can provide to other devices is limited to 5 Gbps.

The AUKEY CB-C55 USB-C hub is currently available from Amazon for $99.99, down $30 from the typical price of the product, which is $129.99, according to the retailer. The hub is backed by a two-year warranty.

    Almost what I need ... almost. I would much rather see this with dual link DVI-I instead of VGA (it's becoming difficult to connect my older but still very good 30" HP LCD) and at least one more USB port.

    You could get an active DP to HDMI 1.4 adapter and use that to connect to your monitor (assuming it's one of the older 2560x1600 monitors). Dual-link DVI is such a niche connector nowadays that I can't imagine a company integrating it into one of these hubs.

    Many older 2560x1600 monitors only support DL-DVI for their native resolution. Some (like my U3011) technically support 2560x1600@60 over HDMI but their EDID doesn't specify support for it. If you're able to set a custom resolution it'll accept it.

    The U3011 is a native DisplayPort display... You can feed it 2560x1600 over DisplayPort. You don't need DL-DVI for that.

    I was looking for the same thing (a hub with dual link DVI) but couldn't find one. I ended up buying a generic one on amazon since I really only need it for my older monitors that are DVI only.

    The real issue at hand is who the eff bought the new macbook pro? ...ripoff/fail central

    I would like a USB C Hub. Every time I see one mentioned, it turns out it's just an other old 5Gbps USB A hub with some aditional (usualy old style or old version) extra display and ethernet pors.

    So far, I have not come accross any proper USB C hub, where the input is USB C Gen 2 and a least 2 of the output (or should I call them input) ports are also USB C 10Gbps.
    Will there be one? I would like a 4 port version.

    Why the hell isn't it 4K at 60Hz? Oh, because Apple cheaped out and limited the USB Type C port to 5 Gbps.
  • Kevin G - Wednesday, March 29, 2017 - link

    The limitation isn't that the Type-C port is limited to 5 Gbs.

    It is a limitation of the DP to HDMI active converter chip in this adapter.

    Not quite.

    There are 4 channels in USB C that can be used to provide Thunderbolt, DP or USB3 or a combo.

    Most use 2 for displayport (so 1x 2560@60 or 1x 4K@30) and 2 for USB 3 speeds. They could have given the hub the ability for 4K displays at 60Hz, but it would have meant only USB2 speeds for those ports / the LAN port.

    The way around this will be Displayport 1.4 when that (finally) goes mainstream, or building the port on Thunderbolt 3 over the datachannels (more cost, but can support 2x 4K@60).
