D-Link DUB-H4 4-Port USB 2.0 Hub

Average rating: Stars

Great for desktops.... less so for notebooks

I purchased this after reading the reviews for a number of USB hubs (really!) I can't use my iPod and 2.5" WD Passport at the same time as my USB mouse & flash drive on the notebook (just two USB ports, both 2.0), and so the purchase...

1. Long USB cable works nicely for desktops, but do I want to carry that around? It might be useful for notebooks with recessed USB ports, but read on....

2. My external DVD writer, 3.5" external HDD work fine w/o the hub powered because they have their own power adapters. My self-powered WD Passport 2.5" HDD and iPod need the power cable to be plugged in. My USB1.1 Lexar flash drive works without the hub powered (mobile for the low-power-draw devices). So: great for desktops, but not particularly mobile.

3. Tested my USB2.0 3.5" external HDD plugged in parallel to the USB1.1 flash drive - both work as expected. USB2.0 - 184 MB in ~1/2 minute, USB1.1 - 4 MB in less time. As another reviewer pointed out, probably depends on the device. This test was without the hub powered (note: not the USB-powered WD 2.5" HDD).

4. The two-pin power adapter is as thick as a three pin plug, but wide. So it will work fine when the flat pins are parallel to the length of the strip, but the adapter will block the adjoining sockets with the flat pins perpendicular to the strip. I have both types of power strips!

Bottom line: it works great with my desktop and my notebook when docked. However, my search for a mobile USB hub continues.

A Great USB 2.0 Hub

This USB hub has worked great for me and my desktop. I orginally had only 2 USB ports and now I have more! Yay! The installation was a snap, mainly because it's USB I'm sure, but it does work great.

I've had zero hang ups or problems with this USB hub, and I'm glad I went with such a small form factor because it doesn't take up much room on my desk.

OK but not great

I purchased two of these hubs based on reviews on this site. For the most part they work well, but there have been problems. My laptop at the office now only recognizes USB devices plugged into the hub. If I plug a device into the laptop's other USB port it is not recognized - it was before I purchased this hub. On my PC at home I continue to have a rare problem with my MS optical mouse working especially after putting the computer into sleep or hibernate mode. I don't know if these problems have anything to do with the hub, but I suspect that they do.
