D-Link DUB-H7 High Speed USB 2.0 7-Port Hub

USB 2.0 provides plenty of speed for fast data transfers. View the DUB-H7 in detail.

Designed to provide quick and easy access, the DUB-H7 offers seven USB downstream ports for connecting USB peripherals, devices, or other USB hubs. A single upstream port connects the DUB-H7 to the host computer or another USB hub, enabling up to 127 devices to be connected by cascading multiple hubs. Configured directly by the operating system, the DUB-H7 operates seamlessly with both Microsoft Windows and Apple Macintosh operating systems. There's nothing to configure -- it just works.

Diagnostic LEDs provide port status for each port, as well as power status. As mentioned, the DUB-H7 is backward compatible with USB 1.0 and USB 1.1, allowing you to connect all your existing USB peripherals while easily integrating with your existing network at home or in the office. See a typical setup with the DUB-H7.

Product Description
The D-Link DUB-H7 2.0 is a hi-speed USB 2.0 7-port hub that is backward compatible with USB 1.0 and 1.1. It provides an out of the box industry standard that allows connection of up to seven USB peripherals or devices to your USB ready PC or Mac. The D-Link DUB-H7 is targeted at PC and Mac users that are expanding the number of USB ports on their system.Designed to provide quick and easy access, the D-Link DUB-H7 provides seven type "A" downstream ports for connecting USB peripherals, devices, or other USB hubs. A single type "B" upstream port connects the DUB-H7 to the host computer or another USB hub, enabling up to 127 devices to be connected by cascading multiple hubs. Configured directly by the operating system, the D-Link DUB-H7 operates seamlessly with both Microsoft Windows and Apple Macintosh Operating Systems.As a standard USB hub, the D-Link DUB-H7 buffers USB data from any attached peripheral in compliance with USB specifications to provide an invisible extension of the USB bus. Supporting both low speed (1.5Mbps and 12Mbps) and hi-speed (480Mbps) devices, each port creates a bridge between the peripheral and host computer.Diagnostic LEDs provide port status for each port and power status.

This item is getting something of an undeserved rap here...   July 3, 2005

I've had one for about six months now, and it's worked without problems. One of the things I particularly like with it is that it comes with one of the newer "slimline" power supplies that doesn't block other plugs, works anywhere in the world (100-240V), and is more efficient than the old "wall wart" power supplies.

Let me address some of the other comments here:

1) For the guy with the Lexar data card... it is a blight on D-Link's reputation that their technical support was clearly incompetent (this is sadly true of many companies today -- being pushed there in part by the relentless "drive to the bottom" by consumers who often care more about price than quality and support), but I doubt that even a really good company could have helped much. Although the hub may have somehow been at fault, it's also possible the Lexar card had problems -- even if it worked fine in other hubs. For the record, I've used a handful of USB drives with this hub without problems... although not a Lexar brand.

2) Regaridng plugging in a USB 1.0/1.1 device and slowing the hub down -- this doesn't actually happen, at least in the hub I received, but what D-Link is doing is hedging their bets (hence the word "may" -- which unfortunately these days many manufacturers use when the word "will" is more correct!): Inside the hub you'll find a VERY generic hub IC (actually, two of them), and D-Link has a lot of freedom to use different vendors' ICs based on price, availability, etc. All of them are USB 2.0 hubs, but ones without so-called "per port transaction translators" will drop to full speed (12Mbps) if any of the ports have such a device plugged into them. Happily, ICs like this are pretty much extinct today (when USB 2.0 first came out they were around). In any case, your solution of just getting two hubs certainly still applies. I agree this should be a little bit more prominently advertised, but so should a lot of things about USB, WiFi, etc. -- the oft-touted data routes of 480Mbps and 54Mbps (respectively) are pure fantasy, for instance, in real world applications.






Works just fine - USB 1.0, 1.1 up to 2.0   March 29, 2005

I currently have 6 of the 7 sockets connected to different USB devices - some 2.0 and some less.

Each works just fine - even the 2.0 high speed micro drive.



DO NOT USE WITH YOUR LEXAR MEDIA JUMPDRIVE   September 12, 2004

I just purchased this item and it destroyed all the data on my LEXAR 2.0 256MB USB JumpDrive. Further more, D-Link was completely unhelpful, with customer serve reps who did not even understand what a USB-Hub (even though I gave them a part number) and kept asking me questions which referred to an Ethernet hub not a USB hub.

I lost all of my dissertation data, let's just hope Lexar has better customer service than D-Link.


Does not work as advertised   July 9, 2006

I have a fairly new high end computer with fewer USB ports than I have devices so I needed to expand. The reviews were great for the D-Link so I opted for this HUB. Clearly a misstake!
I was expecting this unit to work with the following equipment:
IPOD Nano
Canon Powershot
HP Printer
Logitech Fusion Web Camera
Plantronics Headset
Skype phone device (connecting a regular phone to the computer)
The only thing that works without problems is the printer. The IPod is not recognized when plugged in to the HUB but works fine in any of the computer's own ports, the Web Cam takes 2 minutes to be recognized when plugged in to the Hub, the Canon Powershot is recognized but none of the programs used (Picasa or Canons own import software) is able to import any pictures when the camera is plugged in to the HUB and finally the sound quality is affected when using the plantronic's headset.
Further the HUB blocks other built in memory card readers when plugged in in one of the sockets but not in an other and it blocks the BIOS when booting up if the third slot from left is used. Maybe I got a bad one, but one expects the units they sell to be tested before they go on to the shelves.
