Customer Review: D-Link Dub-H7 7 port USB hub
Summary: 4 Stars
The order was filled promptly and as promised. The device plugged in and has worked flawlessly. Both the hub and AC plug are larger than they have to be so it might not be for someone needing it in a tight space but then neither does it flop all over your desk at the lightest touch. It works well as a stand alone charger/power supply for my Sansa USB powered mp3 player.
Addendum:1/8/2011. After a 3 years the hub seems to work ok for some things but I have several that will not function or function poorly while hooked to this hub. Neither of my printers will work when connected to this hub (Canon Pixma MX870 and HP Laserjet P2014) nor will my webcam, Phillips spc 1330. I originally liked this so much I bought another for my wife's computer but did not need it. The new out of the box does the same. All the items noted work fine when connected directly or to a Statitec non powered 4 port expander. Just to eliminate the possibility of the drop from USB 2.0 to 1.1 when usb 1 devices are also connected, I tried the devices with nothing else plugged into the D-Link port. It's been a couple of years so maybe the newer ones have this fixed. It's still a nice usb charger but I'm looking for something else for a powered usb port.
Customer Review: Does not work as advertised

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.

Ok I had a litle Vantec 4 port USB Hub and it died on me. I go to the store and buy a D-Link DUB-H7 to replace the old one. I tough that if I pay more it would be better!!! What a joke! First let me give you my setup: Toshiba Satellite A30 laptop, external 2.5" 20GB and 40GB hard drives, external DVD burner, additional external 3.5" hard drive(ATA) plus a few other device that I use. First of all the 2.5" external hard drive don't work at all. They use 2 USB port (to power the drive 'cause it does not have an external power source). It worked fine with my cheap Vantec USB HUB. The rest of my device (HDD, DVD, Card reader, Wacom tablet...) give me errors (write delay error),(I have XP Home) and corrupt the data sometime. Windows lose the device connection after the error and then reconnect the device. It's not a problem with my laptop. I tried with my other PC (regular desktop) and have the same problems with the 2.5" HDD. The rest of the devices worked seems to work fine until I did a backup on DVD. Some of my images where corrupt.
It look like this HUB work for some people bur not for me.
If you have the same problem, don't think your going crazy.
Do yourself a favor and buy something else.

I have two of these hubs. I also have one of the same brand in a 4 port model. I got them so I could keep my peripherals hooked up to my computer so I wouldn't have to crawl around behind it every time I wanted to transfer from a camera or scan a document. Of all the peripherals I plug in, only two pull their power from USB, a scanner and my room light sensor, so I'm not trying to pull massive power. I do not have them daisy chained, they each get their own ports on the computer. I figured that since these hubs are powered, they could handle the 7 devices for which they are designed. Both of them fail miserably. I've gotten so I fear rebooting my computer, because every time I do something or another is not detected. Usually it's my mouse or keyboard and I have to play Whack-a-Mole with the plugs to be able to even log into my computer. Interestingly enough, the 4 port hub by the same company has 4 peripherals on it and works great. If I plug more than 2 items in each of the 7 port hubs, I get issues.
Get as many 4 port hubs as you need. You can probably daisy chain them conservatively and get much better results than you do with the 7 port hub.
Customer Review: Perfect USB Hub!
Summary: 5 Stars
With SO MANY choices of USB hubs, I had a hard time deciding on a good selection. However, I'm VERY satisfied with this D-Link Hi-Speed 7-port USB Hub!
Why spend $50 or more on a USB hub... the technology is not new, and it is a worldwide supported and implemented standard. My only concern was whether to get a 4-port or 7-port hub. I opted for this 7-port hub, as it was at a great value and manufactured by a trusted company (D-Link makes great routers!).
Although it requires an AC adapter, it is worth it, as it guarantees full power output to each individual port, whereas the USB hubs that don't require an external power source just divide up the power from the single root USB port from the computer, and thus the transfer speed to the devices is decreased and powering small USB devices (such as a fan or light) becomes incapable.
Don't wander around the internet looking for a good-value, reliable USB hub like I did. Trust D-Link on this one. And with so many computer peripherals utilizing USB, you may not think you'd ever use all seven of the ports, but you most likely will down the line!
