The main shortcoming here is that this is a 4-port USB hub, so I expect to be able to use at least 3 ports, right?? But no... I plugged into three ports, and my iPod starting freaking out, "disconnecting/connecting" back and forth until I just unplugged it. Meanwhile, my file transfer from a flash drive died halfway through and when I tried to re-copy the files, the thumb drive folders were all missing (which reappeared after I removed it and plugged it in again).
Also, even if it was the only thing plugged in out of 4 ports, my Western Digital Passport would not connect to the computer. Yet it works fine when plugged straight into the computer.
So I guess if you are looking to connect flash drives only, this might work ok.
Also, beware: Amazon seller Adorama Camera won't accept returns if you open the blister-packaging that it comes in!!
The hub is very small and compact, measuring only about 4 inches wide by 2 inches deep by half an inch thick and resembling a small harmonica. Each port is shrouded with a clear plastic shell that lights up red whenever a device is connected, which I find to be a handy feature (not to mention it looks cool, too). I like the fact that the hub features a detachable USB cable (rather than being permanently attached like less-expensive units), which allows you to easily swap in another cable if you need a longer or shorter cable than the unit comes with. The unit ships with a 5V 2A power adapter which provided plenty of power to run my USB-powered external HDs. The power adapter is in a horizontal orientation which means it won't block half the outlets on your power strip, which is a good design. However, I should add that the barrel plug that connects the power adapter to the hub looks to be smaller than standard; the plug of another 5V power supply (which I use to power 2.5" external HD enclosures) I had was too big to fit in the hub's power port. If the stock power supply should fail, finding a compatible replacement could be problematic. Although the hub can be used without the external power supply (instead running off the 5V power supplied by the USB port), beware that it probably won't have enough power available to run high-drain devices such as external HDs and battery chargers. The unit is marketed as a USB 2.0 hub, but I can't comment on the speed because I'm currently using it with one of my old "dinosaurs" that only has USB 1.1 although I will say that it has thus far worked flawlessly (albeit at poky USB 1.1 speed). Because the unit is so small and light, it has a tendency to move around any time you bump a cable and plugging/unplugging cables is a two-hand operation as it takes one hand to plug/unplug the cable while the other hand has to steady the hub, something that some users may find irritating. Overall, I am very satisfied with this unit and it would be a good purchase for anyone looking for a small and inexpensive yet good-quality powered USB hub. I give it 4 out of 5 stars.
FYI... As is the security standard for a lot of small electronics that are packaged for hanging on the retailer's shelves, the un-boxing process was pretty hazardous. The molded, clear plastic packaging is really tough to break into, and the resultant fractured edges are as sharp as a knife blade. BE CAREFUL!
My setup is as follows: HP G60 laptop with Windows 7 Home Premium Service Pack 1, Microsoft optical wheel mouse, and three Western Digital portable hard drives - an older 360 GB, a 750 GB, and a brand new 1 TB.
When used with the Targus 4-port USB hub, my computer recognized the mouse, but all of the hard drives had issues. Some didn't connect at all while others rapidly connected and disconnected non-stop. I'll admit it's possible it could just be my system, but I did find another hub (see below) that worked as expected. In hindsight, I didn't look for any solutions at the time and I didn't even try a system restart with this Targus hub. Nevertheless, I prefer things to be simpler than that.
I borrowed two other 4-port hubs to try. One was another Targus (different model) and the other was a JustCom (never heard of it before). The Targus had exactly the same problems while the JustCom worked just great for the most part. The JustCom stumbled when I plugged in all three hard drives and the mouse, but works with any combination of three of them even when I add a Memorex 4GB thumb drive. In the end, I traded the new Targus for the JustCom and I'm happy so far.
