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.

    I can't imagine what would follow a USB hub review.
    Maybe an IDE cable "Round-Up"?
    Case thumbscrew "Show Down"?
    Floppy drive "Face Off"?
  • Visual - Thursday, May 22, 2008 - link

    I could use some articles about those topics.

    I can very much appreciate rounding your IDE ribbon cables to save space and make them look cooler, also removing the faceplate of your floppy to make it look geeky, but totally can't figure out just who would I show my case thumbscrews to... can't lure anybody close enough for some reason.

    For me this review is quite useful. Over the years I have bought and used several USB hubs that have different problems. Some don't work with different motherboards, some just will not power up a 2,5" external HDD even when powered directly.
    I buy and recommend many computer related products at work (and to friends) so knowing that there is a hub that WORKS with many peripheries connected is useful knowledge. Besides it's boring to focus only on mobos, CPUs etc.

    I don't know, good motherboards come with at least 6, most have 8, and if you have bought one lately it could have 10. I don't see any need for a hub, but then I don't have more than 10 USB devices that "need" connecting all at once.

    Printer,
    gamepad 1,
    gamepad 2,
    gamepad 3,
    gamepad 4,
    External HDD,
    Music Player,
    USB stick 1,
    USB Stick 2.
    I suppose I could use a USB keyboard/mouse, or an internal SD reader (or my external SD reader).

    In reality if I have many gamepads connected, they will go through a $10 unpowered hub just fine, so all of the USB input devices are only using one. But with the current problem of games supporting multiple players (as in: not supporting multiple players, ask me how a PC is not set up for 4 players, their are high-resolution displays, tons of interfaces, multiple displays. Often the Same game is available on a similar platform, AKA X-Box, and has 4 player support, this is BS)

    To sum up, I don't know of any reason to own a USB hub personally, due to all of my motherboards having 8 ports, a $2 USB port bracket to bring some of the USB header pins to a rear panel, or front panel, is worthwhile in my view, simply because it makes more sense. Most of the people who "need" these smack their forehead and cry "d'oh" when they realize that there are more front panel ports, and a set of unused header pins internally besides.

    I like Rosewill "brand", but I just think USB hubs are stupid (read: inelegant, ugly, redundant, expensive).

    In realit

    It's surprising how quickly the devices can add up:

    Keyboard
    Mouse
    Gamepad
    Printer
    Scanner
    Modem
    UPS communication
    Camera cable (not needed all the time but convenient to leave plugged in the PC)
    TV-tuner stick
    Memory-stick for Vista ReadyBoost

    That would be all ten of my ATX mobo USB ports used up (six on the back of the mobo, and two on the front of the case plus another two in a 3.5" drive slot adapter which came with the mobo). And as the TV-tuner stick blocks access to either of the neighbouring front connectors (and it needs to be at the front to receive the IR remote control signal) I would actually need 11 USB sockets.

    In reality I connect my keyboard and mouse using PS/2 sockets, my modem by ethernet, and I don't use Vista so no memory-stick for ReadyBoost, but that still comes to six USB devices. Also my monitor has a 2-port hub so that adds one extra socket in total, though I don't use it).

    Some budget PCs don't have six USB sockets, and I suspect many laptops have less than six, so there is a market for hubs.

    I'm guessing you don't own a laptop, or don't connect much stuff to it. USB hubs are very useful there since laptops don't have many ports, and a hub also makes a cheap docking station in that you can connect a bunch of devices with one plug instead of several, even if the laptop has USB ports to support them.

    It's no longer fun waiting almost 2 months for the additional results from the testing of the Western Digital 640GB which would be "coming soon"... Nor for the comparison of the AMD 780G motherboards coming in "the near future" 2 weeks ago now :-(

    Could you guys please concentrate on what you have begun?
  • cghebert - Tuesday, May 13, 2008 - link

    I very much second that notion.

    Did I just read a front-page article on Anandtech reviewing a USB hub????

    I understand that I (and many other old-time regular readers) are not the target demographic for such things, but I'm having a hard time seeing who is.

    My mom would be an example of someone who may need a USB hub, but wouldn't have a clue about what one is or really does, but she also wouldn't care about how many seconds it took to transfer what file, what the real (vs. theoretical) maximum throughput is etc. etc.
    And besides, it's a moot point because she would never visit this site in the first place.

    I'm not annoyed by this, I'm just very very curious as to your reasoning: is there a new direction Anandtech is heading towards with articles like this?
    i.e. more frequent, short and simple reviews of every day devices that might appeal to a broader casual audience? (ala CNET, for example)
  • DigitalFreak - Tuesday, May 13, 2008 - link

    It's interesting in the fact that now I know that this hub will allow me to plug in multiple USB devices and not have them run like crap.
