Perfect for my needs where laptop contains only two USB ports and one is always dedicated to the printer. Been using for several weeks and all going well. Only fault I find is no on/off switch.
I've had four devices (2 external 250GB drives, wireless keyboard/mouse receiver, all-in-1 scanner/printer) running always on and connected to my laptop for months, with no problem. I'm buying two more.
As soon as I connected the H-4 to my computer all of the LEDs came on so I plugged in my devices. I'm using it to connect an HP printer and an APC UPS to my main computer. I've only had the D-Link DUB H-4 for about a week. Both of them work just fine, so I dont plan on using the adapter unless I connect a device which needs power. Another reviewer noted that the AC adapter didn't seem to be necessary for the hub to function. I can definitely second that. The printer and the UPS are hardly data intensive devices so I cant comment on the speed. Overall I'm pleased and would recommend the DUB H-4.
I bought this to run external hard drives and needed a high speed connection. This hub has worked perfectly and was a snap in install.I'm running this on a home computer and not a laptop.Highly recommended if you're going to connect this to a desktop computer and need fast, usb 2 connections.
D-Link DUB-H4 High Speed USB 2.0 4-Port Hub The D-Link four-port high speed USB hub arrived right on time. It came in good condition was exactly as promised. A quick plug-and-play and my USB 2.0 connection problems were solved.
