USB 3.0 hub question
I'm thinking about buying a USB 3.0 external hub for my pc. I'm
looking for one that has about an 18 to 20 inch cable length and will use the older 3.0 USB connectors (Type A ???). Are there any hubs being made that fit those conditions? Who is making them? The ones I saw at newegg look to have cords about 6 inches long. That is not long enough given where my pc is located. FWIW, my mobo does not have the onboard UsB 3.0 connector to enable using USB hubs that fit into 3.5" and 5.5 bays. Thanks, John |

Thanks, John FWIW, if you find a hub that you like "except" for the length of the cable, there are USB3 "extension" cables (male/female) of whatever length you need. |

Thanks, John The hubs with the captive or attached cables seem to be relatively short. The ones that list the word "detachable" seem a bit longer. Try "USB3 hub detachable" in a search. https://www.newegg.com/Product/Produ...9SIA5MP7AR8593 There's no particular technical reason for these choices. They could use a 3 meter cable, at which point the dielectric properties would have to improve before the cable could be made longer. Paul |

The OP never mentioned which USB hubs (or USB switches) he looked at on Newegg's web site. There are plenty that do NOT have an attached USB cable. In fact, those with an attached cable are usually meant for portable use with laptops, netbooks, etc. Typically a desktop USB hub/switch has no attached cable and you attach whatever cable you want to connect it to the computer. |

Are there any hubs being made that fit those conditions? Who is making them? Get a hub that has no atached cable. Then attach a USB 3.0 cable of the length you desire at a maximum of 3 meters for a passive USB3 cable; see http://www.yourcablestore.com/USB-Ca...m_ep_42-1.html If you will be attaching more than one high-powered USB 3.0 device to the hub, make sure to get a hub that is externally powered and whose walwart is rated for N x 900 mA, where N is the number of ports on the USB hub, so each USB 3 device can have full power from the hub. If the hub has 4 ports, you want the walwart rated at 3.6 amps, or higher, for its *output* load (to the USB hub). If one of the ports is a high-amp charging port, you'll have to add its amperage (2.4 A) into what the walwart must support for the total load of all ports in use on the hub. I've seen 4-port USB 3 hubs externally powered with a 2.4A charging port but the walwart was rated only for 2A which isn't even enough for the 2.4A charging port. Without external power to the hub, the hub will only get the 0.9A load across ALL its ports from the USB 3 port into which you plug the hub. That is, all USB devices (2.0 or 3.0) will have to share the single 0.9A maximum load from the one USB port on the computer. The ones I saw at newegg look to have cords about 6 inches long. That is not long enough given where my pc is located. FWIW, my mobo does not have the onboard UsB 3.0 connector to enable using USB hubs that fit into 3.5" and 5.5 bays. To what would you be connecting the USB 3.0 hub if your computer doesn't have any USB 3.0 ports? Mobos I've seen that had USB 3.0 support had a USB 3.0 header for support of front-panel USB ports. Perhaps you have a mobo that is devoid of USB 3.0 support (it only supports USB 2.0) and you installed a daughtercard to add USB 3.0 support. That daughtercard doesn't have a USB3 header or an internal USB3 port? |

The one I tried (Wavetek??) seemed to be unreliable with my USB 3.0 drives - got error message. Worked OK if plugged it in USB 2.0, but that of course defeats the reason for me using it. John |

After I posted, I did check Best Buy (not my first choice or even second choice of vendors) and found they categorized their hubs by "stationary" and "portable (??). BB did list a stationary hub by Insignia that commenters report it has a 3' cord. Newegg does not carry that item. They did have a USB 2.0 hub. John |

The location of my pc is such that I estimate I need a cord length of 18" to 24" inches so that I can put the hub on a stable, flat surface and attach devices as needed. John |

The mobo does not have the onboard port required to connect more USB 3.0 ports as in one of those USB hubs that mount in the pc chassis bay (either 3.5" or 5.5"). Because of the location of my pc, using the rear USB 3.0 ports is very inconvenient. I've tried a USB 3.0 extender cable and had mixed results. It works with my ext HD if the HD is plugged into a USB 2.0 port. OTOH, the drive is not recognized when the drive and extender cable are plugged into the USB 3.0 port. The Insignia hub I referenced in a reply earlier has a separate power supply, and commenters raised the 3.5 amp issue you raised. At the moment, I don't know how many devices I might use on it, much less simultaneously. In practice, I'm trying to make sure that devices I add in the future are USB 3.0. John |

Not necessary. As noted, I already went through them looking for length of the cord. So why not look at the ones that do NOT have an attached (permanent) cable to the USB hub? A permanent cable rather limits the flexibility in where the hub can be positioned. They were too short for my use. After I posted, I did check Best Buy (not my first choice or even second choice of vendors) and found they categorized their hubs by "stationary" and "portable (??). BB did list a stationary hub by Insignia that commenters report it has a 3' cord. Newegg does not carry that item. They did have a USB 2.0 hub. Just because a hub lists an included cable does not mean the cable is permanently attached to the hub. For example: https://www.newegg.com/Product/Produ...01&ignorebbr=1 That comes with a 1-meter USB3 cable but it gets plugged in on the backside of the hub. https://www.newegg.com/Product/Produ...0079080%208000 There are many there that have non-permanent (detachable) input USB3 cables; i.e., they have a USB3 port to connect via whatever cable you want to use to the computer. You can get micro-B to type A USB cables of varying lengths. For example: https://www.newegg.com/Product/Produ...82E16812225081 https://www.newegg.com/Product/Produ...82E16812423106 I use double-stick velcro strips to affix the hub atop the computer case rather than clutter my desk, so the cable only has to be long enough to reach from the hub to the backpanel or daughtercard USB port. Also remember that with a hub that it will share the bandwidth of just the one parent USB port to which you connect the hub to the computer for ALL of the hub's USB ports. Anything that generates lots of traffic, like printing, file transfers to hard disks, especially with both on the same hub, and a USB network adapter will generate high volumes of traffic that will choke the bandwidth available for the remaining ports on the hub. Ports on a hub do not communicate with each other; that is, you cannot short-circuit the data path of, say, a file transfer between two USB devices on the same hub. |
