Summary: Wrote D-link 3 times for customer service... never heard back last letter below: Third and last time: I have sent 2 times by this web site and one time by e-mail and have never heard back!!! I have a dub-h7 usb hub, purchased 12/26/2014 and it has stopped working all of a sudden. It will charge devices ok on the 2 charge ports but will not communicate with the pc. I have tried a different usb cable that I have and still will not work.
Summary: I didn't realize that I had a preferred port orientation until I started plugging in dongles and flash drives with status lights. It looked quite silly with all those status lights facing downwards. It's a deal breaker for me and I will be returning it. Call me fickle, but anything that takes up space on my desk permanently needs to be both functional and cool! Since it's going back, I'll note one more frustration.
Pros: Quality look and feel
Cons: Upside down ports No port status lights Very light
Summary: It's a nice, cheap little hub but only useful for uni-directional use (i.e. charging your iPad or iPhone).
Pros: It's small for the number of ports and two of the ports are fast-charge ports.
Cons: It's only USB 2.0. Also, the uplink to the PC doesn't handle both upstream and downstream traffic. If you transfer data from a thumbdrive connected to the hub to a thumbdrive connected to the PC, then the data transfers as expected. If you transfer data between thumbdrives connected to the hub, then the data transfer is slow - in extreme cases, one of the two thumbdrives loses its link to the PC.
Summary: I got two bad hubs from D-Link, one destroyed a tablet another is whacked out. Not touching another D-Link USB product again.
Pros: Lots of USB ports.
Cons: Ports work sometimes and don't work other times, as many of the other reviewers have stated the thing constantly connects and reconnects devices and it self with nothing plugged into the hub on my desktop PC. I also have a second of these D-Link hubs that I use with a Surface Pro… One night when I plugged it into the Surface I heard a pop and the backlight on the screen went dead. Not realizing that it was the HUB I sent the Surface back for replacement. Got the new S...
Cons: I use D-link products and love them but this thing is trash and a total disappointment, Just like other reviewers have noted, this hub constantly loses connectivity. My machine keeps rediscovering my android phone every few seconds. and the same goes with any other device I plug into it. Absolute JUNK. I have a hub I got on a famous auction site that ends in "bay" at half the price that works flawlessly. Don't waste your money on this item.
Pros: Bought this to use with my Raspberry Pi. Had been using a cell charger but ran into issue with it freezing. With the external power plug this provides enough power to run the Pi and still handle plugging other devices into it. The size is tiny. Fits perfectly on the case for the Pi. Now I only need to get a shorter USB cable to run between them.
Summary: This feels like it may be a manufacturing flaw in this device, but it could be a design flaw.
Pros: Convenient, compact, lots of ports, usable for charging MP3 player
Cons: Loses connections intermittently when used with a MacMini. Have repeatedly had to unplug and replug USB keyboard to get it to recognize. Happens erratically when the Mac goes to sleep or is turned on. Usually removing the USB cable from the hub does the trick, but one recent time I had to restart the Mac to establish a connection to the keyboard. Some trouble with mouse and USB external drives, but the big problem is with the keyboard. This is an intermittent problem,...
