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 High 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.The DUB-H7 includes a Quick Install Guide, a 6-foot Hi-Speed USB 2. 0 certified 'A' to 'B' cable, and an AC power supply. Most Helpful Customer Reviews 203 of 207 people found the following review helpful: Two features worth noting       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. 415 of 431 people found the following review helpful: This item is getting something of an undeserved rap here...       This review is from: D-Link DUB-H7 High Speed USB 2.0 7-Port Hub (Personal Computers) *** 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 1.0/1.1 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. 144 of 146 people found the following review helpful: Good product, but laptop users beware 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. Most Recent Customer Reviews Heavenly!!!
