The Rosewill RHUB-310 series features seven USB 2.0 ports and is capable of bus-powered or DC adapter operation. When operating in bus-powered mode, the unit draws all of its power from the host computer's USB interface. USB current (power) specifications are allocated in units up to 100mA with a maximum available of 500mA per port in a compliant design. As such, a bus-powered design is limited to at best four downstream ports since it cannot provide more than four connections of 100mA to downstream devices. Rosewill provides a 2A power supply for the unit that will fall short of the maximum 3.5A draw if all seven ports are populated with devices that require the maximum 500mA per port.

google. are YOU lazy?possible query: "usb devices running slow (on) hub" or "why is [device x] slow (on) usb hub"

It was short and sweet and got to the point. It Let us know about a new product that some one might use. Not everyone has a new system. I have been a member since this site started and I come back to it all the time. It was because of this site that I was able to learn and build my first computer(way back when). This site use to have articles for every level. I for one think this site needs to have a few more articles for the newbies so that they can learn and become advanced.bakerzdosen - Tuesday, May 13, 2008 - link
Well, I personally would have liked two things:1) Test it with a bus powered scanner (like a Canon lide). That's the only problem I had when hooking up my mother's USB hub, was that her scanner wouldn't do full scans (previews were fine) via her D-link USB hub I just bought for her - even when powered.
2) A picture/description of the power brick. Smaller is definitely better here, and it seems that they're all out of control in size taking up 2-3 outlets if you use a UPS or surge protector.

Cool review, I just bought another hub with fewer ports and no power source for just as much money. My bad...impulse buy.Most important about the review is getting a little attention to the Rosewill brand. I have bought serveral of their products and have always been amazed at the value. These guys seem to launch one good product after another. I have several external disk enclosures that work, are well built of high quality materials, are beautiful as objects, and were releativly cheap compared to other lesser products. Even the least exspensive of their product range has always impressed me with high perceived value.
You don't see this brand marketed widely, if you do find something they make give them a chance I think you might be pleased.

I purchased one Rosewill external enclosure for personal use, it has been fine. I purchased another for the lab, and two Samsung hard drives have died in it. Suppose the drives could have issues, but seems a big coincidence.RamarC - Tuesday, May 13, 2008 - link
a usb hub? i could understand a wireless usb hub since they're somewhat leading edge, but a run-of-the-mill wired usb hub?there are already plenty of sites that do 'reviews' of mundane components. stick with hardware reviews for the enthusiast and the IT community.

My assumption is that Gary needed a USB hub at the lab, and that since companies send AT hardware all the time, he decided to do a three-page write-up on the hub he selected. I don't object to that, so long as the next great GPU or CPU review isn't delayed.Visual - Tuesday, May 13, 2008 - link
How about test with multiple ports used at once? Like two drives, a drive and something low-bandwidth, or even all 7 ports used at once?Also I'd like to see results not in seconds, but in kbps, just to show how close to the theoretical 480kbps the thing gets. Well yeah, I can recalculate it myself, but... you could too.
