OK, but some problems |
|
The D-Link DUB-H7 USB hub works well once it the cable is connected to the computer, but ONLY when you insert it after booting up the computer. I am using it on a Imac and if you connect the cable prior to booting up, the computer fails to boot. This is not a problem only with my computer, as my son-in law also has the same problem on his IMac. Also, flash drives may not be recognized if connected to the hub when you insert the cable to the computer and you may have to remove and reinsert the flash drive. External hard drives seem to be recognized with no problem. I don't know if this is a problem with a PC, but be aware that this may happen. |

Toughness over feature |
Having owned 2 of these units for more than 2 years now, I am finally ready to review this. My config link two of the same hubs.
Pros:
1.) Very cool looking hub.
2.) No overheats, no matter how many devices of different types are doing transfers. I have done as much as 5 usb thumbdrives full transfers at once before.
3.) Great for devices that doesn't require high speed: scanners, security dongle keys, controllers.
4.) One very tough hub. In the past I have had hubs that occasionally act up with out of control lights etc. This one is consistently in the same mood every day.
5.) Very light.
Cons:
1.) When any usb 1.0 device is plugged into the hub, it runs everything at usb 1.0 speed. Doesn't matter the order.
2.) Even when 2 usb hubs are connected to one another, the speed of both hubs will drop as soon as something usb 1.0 is plugged in. Doesn't matter which port on which hub.
3.) Even when running at usb 2.0 speed, it cannot match regular usb 2.0 data transfer speed of you plugging a device directly into the motherboard ports.
4.) For some reason western digital Mybook storage devices really struggle with this hub. It maybe just my storage device?

It works |
Not too much to add. I plugged it in, & it works. I'm able to plug in all my USB Devices now.
I don't have a lot of space, so the small footprint is great. |

The best |
After repeated failures of other brands of USB hubs I bought one D-Link to replace a cranky one. It performed so well I replaced all the other hubs on my system with a second D-Link. After 2 months there has never been a failure. Good product, highly recommend it.

Works perfectly first time, every time |

I should have bought this first! I got some cheap junk from an EBay seller and it didn't work. This worked first time and worked perfectly. I'm very happy with it. |
