The D-Link DUB-H7 Highs Speed USB 2.0 7-Port Hub works very well as its description.

I found myself constantly unplugging and plugging devices back in to get them to be recognized, because this hub seemed to lose the connection.

*** Note: Several recent comments have stated that this product no longer comes with a worldwide voltage input (100-240V) power supply. That's a shame, and I'd definitely knock a star off the review if I could due to this change on D-Link's part -- I can only imagine it was part of a cost-cutting move. :-(

(Note that this review was originally posted in 2005, so it's been a LIFETIME for an electronic device and the DUB-H7's you buy today are likely quite dissimilar insofar as their physical construction goes compared to the ones from 2005.)

Original review:

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.

I think the other reviews largely get it right. Two things I haven't seen in them, however: first, the plug on the power cord is in the shape of a wide black monolith, so, like bulky a/c adaptors... Second, the included documentation says that the hub will revert to a USB 1.1 hub FOR ALL DEVICES if you have any USB 1 device connected. It says that to get USB 2.0 throughput, you must disconnect all USB 1.0 or 1.1 devices from the hub first. That's worth knowing.

Finally, if you buy the hub, I suggest going to Windows Update and downloading the optional USB 2.0 fix for WinXP SP 1.

I bought this product to work with my Dell Inspiron laptop running WinXP Pro. So far it works great with my wireless mouse, keyboard, and digital camera plugged in simultaneously. The AC power ensures that your USB-powered devices will work properly. However, there is one issue to be aware of: this hub only works when plugged into AC power, which was not clearly indicated in the specs. For this reason, it is not a good hub for laptop users on the go, which is why I give it only 4 stars. Other than that, it is a solid performer. It is small, so it doesn't clutter your desktop too much, and has rubber feet to keep it from sliding. The AC adapter is sideways so that it only takes up one plug, which is a nice detail. This would be a good choice if you are planning to use it for a desktop, particularly if you have several USB-powered devices.

I originally purchased this hub to make it easier to use multiple USB devices with my laptop while using it at my desk at home. My printer, mouse, barcode scanner, and thumb drive are all USB devices, and pulling the laptop out to unplug one and attach another was getting rather old.

It's a smallish hub, but not one so tiny that the ports are so crammed together so as to be nearly useless. At 4 inches wide and less than an inch tall, the hub should easily fit on any desk, and the rubber feet help hold it in place. The ports are widely enough spaced that you shouldn't have a problem attaching cords, thumb drives, or other USB devices.

Since I planned to use it only at my desk anyway, the caveat that an A/C adapter is required didn't bother me--but I've found that the hub works fine without any A/C power at all, and despite the instructions claiming it doesn't draw power from the USB bus, the power LED lights up, and all devices work fine. Without the A/C adapter in use, the hub also runs quite cool and doesn't suffer from the lock-up problems others have mentioned.

If you plan on using mostly powered USB devices--like printers, external hard drives or CD/DVD drives--you should be fine using the hub "unpowered." Using it for a keyboard, mouse, barcode reader, and thumb drive may require the use of the A/C power for reliable operation. And if you're worried about putting too much of a power strain on your laptop's USB bus, connect it via a docking station (as I do) or use the A/C adapter. Still, with that said, many people should be able to use it just fine without having to add another bulky "leech" to their power strips.

The product is and does what all the descriptions say. Looks good, nice and small etc. etc. It is, of course, backward compatible with USB 1.0 and 1.1, but I got a nasty surprise when I opened the box and read the "Quick Install Guide". Under the "tips" section, they state: "Connecting USB 1.1 devices to the DUB-H7 may cause all USB devices connected to the hub work at USB 1.1 speed. To ensure 480Mbps throughput for your USB 2.0 devices, do not connect USB 1.1 and USB 2.0 devices to the hub at the same time." Maybe this is common knowledge to a computer expert, but to me it wasn't! I have 1.1 and 2.0 devices which I want to connect, and now I have to start unplugging and re-plugging devices constantly? That's why I bought a hub with 7 ports in the first place! If I had known this, I would have bought two 4-port hubs: one for my USB 1.1 devices, and one for my USB 2.0 devices.
