The hub itself is clear plastic and you can see all the lights working. It was very simple to install, there wasn't even any hardware to configure through windows. Just plug it in & boot back up & viola!! That simple. Now I have extra usb ports for my ever growing usb peripherials.

-Sylvia quote

I'm using this D-Link USB hub running off of a D-Link 2-port USB PCI adapter card. I had an external floppy, an MP3 player, and an excellent Philips webcam plugged into it. Initially, it would sometimes have trouble supporting all three devices at once, especially the webcam and MP3 device together. Okay, so I learned not to have those two plugged in simultaneously. Then I started getting crashes with them plugged in while the external floppy drive was in. Okay... so I just plug one in at a time. Then the floppy drive, the only device plugged in, would be unable to read a second floppy when switching floppies, crashing the system in the process of trying to read the second floppy. The past week, I cannot even save a 22KB file to even the initial floppy that I insert into the drive that is running of this hub, without some error popping up about the Hub, and locking the system. I have since disconnected the Hub, and have been running the floppy drive directly off of the internal D-Link PCI/USB adapter card, and the drive is working fine without hiccup or any other problems. So... while I could have given the device a medium score for initial installation and use, subsequent troubles and trouble-shooting has turned it into a poor ease-of-use device, and ultimately poor performance. A BUSLINK hub I use at work performs great, running four varied devices without any "issues" - will probably get one for home...
