Kensington PocketHub 7-Ports Portable USB Hub (33366)

Pros- Looks good and works well, very solid construction.- Ports spaced out well.- No annoying lights.- Self powered, but comes with AC. So far have not had to use it. Powers a few flash drives, keyboard, mouse, iPod w/o AC.Cons- Power brick is huge.- The aluminum casing could be better polished.- No rubber feet, the hub slides on the desk and may leave scratches.I'd prefer 4 ports on back and 3 on front, or at least 1 on top, but it will do.

For those Apple Macintosh iMac users who are having trouble with this hub:When I first got this USB hub (Kensington K33366) I had trouble. I have a flat-screen 800 MHz Power PC G4 iMac, the first one sold, with 15" screen. Am running Mac OS 10.4.11. This computer has 3 USB sockets on the back of it. I had my keyboard plugged into one, my printer plugged into another and a Belkin USB powered hub plugged into the third, with my Kensington Orbit Trackball plugged into that hub. This has always worked. Even after the AC power unit that ran the hub failed. I unplugged the AC power and the hub still worked, until I tried plugging in my digital camera to transfer pictures from the camera to my computer's hard drive. Then it did not work. I had to unplug the hub and plug the camera directly into the computer every time. Not wanting to have to do this every time I hooked up my digital camera to the computer, I ordered a Kensington 7-port K33366 powered-hub. I plugged this unit into my computer and my Kensington trackball into the unit. I do not keep my computer on all the time. I turn it off when not using it. I have my computer plugged into an AC extension outlet with surge protector that has an On/Off switch. I plug everything else involved with my computer that needs AC into the same AC extension outlet, such as my printer and high-speed cable Internet modem and the Kensington powered USB hub. Thus when I turn the AC extension outlet off, all units lose power. (This is also very handy during thunderstorms, for safety-of-computer-hardware purposes!)When I tried the new USB hub using this setup, every time I turned the AC extension outlet on and then turned the computer on, the cursor froze. It would not move! I would have to unplug the trackball from the hub and plug it back in for the cursor to move. Nothing I tried, other than unplugging and plugging-back-in the trackball USB cable, would unfreeze the cursor. Until I decided to plug my Kensington trackball directly into my computer and my printer into the Kensington hub. Then it worked! Now the cursor is always unfrozen! Not only that but the printer also works! I do not have to unplug the USB cable from the printer to the hub and plug it back in! I always turn my printer off (or it turns itself off) before turning the AC extension outlet off so the printer can cover up the printer ink-jet orifices so ink will not dry out. Hence, the computer is on and warmed up whenever I turn the printer on.What I think is happening with the K33366 hub is that it needs to be on and in communication with a working and warmed-up computer for the computer to recognize that the hub, and whatever is plugged into it, exists, whenever a device plugged into it is turned on. When I had the trackball plugged into the hub and turned the AC extension outlet on and then turned the computer on, the computer had not yet warmed up enough for the USB hub to be in communication with the computer when the hub was trying to communicate to the computer that a trackball was plugged into it. However, when I had the printer plugged into the hub, the computer was warmed up and could recognize the hub and the printer when the hub tried telling the computer about the printer!Hence, in order to use this particular USB hub correctly, you must use it in such a manner that whatever you have connected to the hub is turned on after the computer is up and running! Do not plug your keyboard or mouse or trackball into the hub. If you do this, it should work very well, indeed!It's a great hub, once one learns how to use it correctly!

Not that great of an item. When I wanted two external harddrives hooked up, it would drop one, so I could not transfer files in between them, even though I had the external power connected. Before when I did not have it connected, it would not even pick up the external harddrive (I have seagate and western digital both 320 gb). I bought this so that I would not have to hog both of my ports and connect several harddrives, but I guess it takes up too much power for the hub to handle. A bit disappointed, but it's not that bad of a buy.

5/5 stars. Nice attention to detail. The "wall wart" is the type that sits sideways as to not obscure the adjacent sockets. Nice long cable for power, as well as a decent sized USB cable. Windows XP detects this and installs as plug-n-play, which says a lot (Microsoft sucks at driver support!) I run a ton of audio devices off this, as well as a webcam on a 10'+ extension. Before my devices crapped out when putting any kind of extension, now, hub near-full, I can extend no problem. I couldn't find any numbers or spec sheet, nor have I hooked this device to a multimeter, but I believe it is up to USB spec. If not, I'm quite confident it's as close as you can get for the money. The stainless casing is solid as well. No complaints whatsoever. I have used this device for about two months.EDIT: Been using this device for three years now, still no problems, BUT BEWARE, I hear they've changed this product and it doesn't put out as much power now.

I like the style and looks because it looks nice attached to my iMac stand (via velcro). However, it does NOT provide enough current to charge an iPad (2.1 Amps). In addition, sometimes (only sometimes), my iPhone will display a message saying the cable (from the Apple store) is not compatible and iTunes does not detect the iPhone. Plugging the same device and cable into the port the PocketHub is plugged into works fine.

i love this product. but i have a problem. i just bought 2 and a friend of mine brought it to me in brazil. but one of the switching power adapter doesn't work. so sad. now i'm looking over the internet where i can find this kind of power adapter.but the kensington pockethub is perfect. =^D

I bought 4 of them (3 from Amazon after initial purchase somewhere else). The hub has seven inputs as opposed to four. We are in era of many USB devices so four might be sufficient sometimes, but not for someone runnig computer studio with number of printers, scanners and input devices it is not. This thing can be stacked, because there is no fancy shapes and inputs all over surfaces like in many other similar but funky products. Performs well with majority of USB devices except those that can work exclusively with computer hub directly. It helps to reduce number of cables (one would require twice more power cables for hubs if used 4 input hub). The power cable uses "brick" power supply so the power plug is small and it does not interfere with other plugs in adjacent outlet.
