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

    08-10-08

    Duration of ownership: 2 Days

    Strengths: Ports stacked vs side by side, ports all on one side, pwr & individual port LEDs not found on most units at this price, compatible w/Mac & PC new & old, backwrd compat w/USB 1.1

    Weaknesses:None

    Overall Evaluation: I did a lot of research before buying. Dumped my 1.0 hub and bought 2 of these. They work great. A lot smaller than it looks in the photo (4" x 2"). So far I've tried 10 different devices (old and new), and they all work fine. I think the person that dinged this unit because of power limitations had a lemon or some other problem. The power light shows when you plug in the included power supply - the other lights and ports activate once you connect the included cable to the computer. The power supply appears to suppliment the amp load. You cant test "load" with a meter (they must have tested voltage which is not viable), but I can tell you that I'm using all ports and I've got several power hungry devices that use 500ma per port or more, and have experienced no problems.

    Duration of ownership: 7 Days

    Strengths: It has seven USB 2.0 ports.

    Weaknesses:On mine, the power supply only powers the 'power' lamp on the hub, and does not power the actual USB hub ports.

    Overall Evaluation: The power supply only powers the 'power' lamp on the hub, and does not power the actual USB hub ports. Therefore, after installing a few devices, there isn't enough power to go around and some devices are not recognized. (I tested the power coming out of the ports, and there was none.) Perhaps I am not the only one getting a 'lemon.' I would think some of the connectivity issues experienced by others may be because of this same flaw.

    Duration of ownership: 2 Months

    Strengths: Small size, port layout

    Weaknesses:problems with SanDisk flash drives

    Overall Evaluation: I did not have any problems with this device until I started using it with my Sandisk cruiser and mini cruiser flash drives. I can read fine, but when I delete files or write to the flash disk, the computer drops the device. I've used the hub on 2 different systems with similar results, both running XP Pro. Other devices on the hub with no issues are a Maxtor One Touch, mouse/keyboard, and 2 printers.

    Duration of ownership:

    Strengths: Compact size, vertical ports

    Weaknesses:None

    Overall Evaluation: Out of curiosity I connected the hub to the computer rear USB 2.0 port without providing AC power to the port. WinXP recognized it without any additional software and all the LEDs lighted up. So I have it working without AC. A joystick, scanner, digital camera and a Jumpdrive are connected to it (Joystick and jumdrive draw power from it) and I don't have any problem with it.) I tried file transfer speed and it took 45s to transfer 300Meg file from hard drive to jumpdrive. Same time with and without AC power. I don't quite see the reason for all the LEDs in there. In my case all of them are constantly lit, even when my computer is turned off. With modem LEDs, optical mouse LED and now USB hub LEDs constantly on, my computer room is pretty well lit up now!

    Duration of ownership: 4 Weeks

    Strengths: reliable device, fittable design for any silver lian-li pc case

    Weaknesses:may be overloaded if used for charging devices like handhelds via usb port

    Overall Evaluation: This USB hub is one of the best I've ever tried. It works perfectly fine however you should watch out for using its ports for charging other devices with mini USB cables (cell phones, pdas, bluetooth headsets) because it may be overloaded.
