Using with a USB Hub

Hi. Right now I have an old iMac, and I use a USB hub (I have way too many USB devices that I like to have connected at once). If I were to switch to a Macbook along with one of the new 24" LED displays, would I still be able to connect the USB hub to the back of the display, or should I not do this since the display technically functions as a USB hub itself?

USB hubs can be used with other USB hubs as long as the hub they plug into has power, such as the display hubs.

  • Satellite M300: speach recognition works only with external usb hub

    Hi All
    I have the Satellite M300 which I was able to operate the speach recognition program prior to having the motherboard replaced due to the usb's failing.
    I have found using the headset I cannot achieve high enough quality to operate it.
    The only way I can operate the speach program is use an external usb hub with its own power supply.
    Would the problem relate to the audio card or just simply not enough voltage?
    And is there na fix?
    Cheers

    Hi
    The notebooks USB ports provide a standard power of 500mA.
    As I said this is a standard but in different cases the external 3rd party USB devices need more power.
    For example one of my external USB 2.5 HDDs must be connected to two USB ports at the same time to ensure that the HDD would get enough power to work properly.
    Your external card is not known to me but possibly it needs more power as usual.

  • Possible USB port damage using non-powered USB hub?

    Referring to the recent discussion on ruining firewire ports with damaged peripherals, a related question concerning the possibility of damage to the USB port:
    http://discussions.apple.com/thread.jspa?messageID=7948387#7948387
    I have an old iPod Shuffle, USB only, and a camera card reader, both of which which get pulled and connected "on the fly" to a bus powered USB hub which is attached to one of the USB ports on the iMac. Am I risking similar damage to the iMac USB port, itself, if something goes bad on the Shuffle or the card reader? Should I be using a POWERED USB hub to avoid direct damage to the iMac USB hub? (And, assuming it will have to be USB 2.0, will it be backwards compatible to USB 1.1?)

    No, my belief is that FireWire devices are more prone to damaging the circuitry behind the port due to connecting and disconnecting on-the-fly (compared to USB). There is supporting documentation on the web, for example.
    http://www.wiebetech.com/whitepapers/FireWirePortFailures.php
    http://lowendmac.com/misc/03/0421.html
    (there are many more)
    Mechanical failure (wear and tear) through constant plugging and unplugging is a secondary consideration.
    If your FireWire device is constantly connected, this issue does not exist (and there is no wear and tear either). On my Intel iMac, my external FireWire drive is always connected, and I use the direct port on the Mac. If I ever need to disconnect it, I shut down my iMac and then disconnect. The other FireWire port is connect to a hub, and that is where I connect and disconnect FireWire devices on-the-fly (old iPod, small bus-powered drive, and video camera).
    If your iPod shuffle is the old +thumb drive+ style with the USB plug, you should be using a self-powered hub. That may be why it is not reliable. Also, that plug on the old shuffle is the most likely part to fail, so it is possible that it is getting worn out. I bought a bunch of used and reportedly broken iPod shuffle (the older white type) on eBay to see if I could fix any of them. I would say, 80% of the time, it was broken due to a faulty USB plug (no data connection). On the rare ones broken for another reason, I used that good USB plug to get another shuffle working. (A few worked after using the iPod Reset Utility, without any other repair. )
    But I'm getting off topic with the shuffle talk...

  • Time Capsule compatibility with Wireless USB Hub

    Is it possible to use a wireless USB hub with the Time Capsule? I am thinking of using a Belkin wireless USB hub, which would have the USB receiver/antenna for the hub connected to the TC, and my printer connected to the hub.
    Below is the link for the Belkin Wireless USB hub that I wanted to use:
    http://shop3.frys.com/product/5845573#detailed
    My reason for doing this is because I want to keep my wireless printing capabilities, but I want to move the TC downstairs and "bridge" it with my AT&T U-Verse wireless router/modem. At the moment I am not able to have my TC and router/modem in the same room.
    My thinking is that this will not work because the TC will not recognize that type of USB device (i.e. the USB receiver/antenna for the hub). But if this works this would solve a great deal of logistic problems.

    I still have questions about how to connect the Brother printer through ethernet. When connected does the airport utility have some area where you can identify the printer as a network printer as opposed to USB?
    The AirPort Utility would only come into play if the printer was attached to the TC's USB port. Printers, attached by Ethernet, would have to "network-ready." Controlling these types of printers would be through the printer driver that you would access through the operating system interface.
    In my HP example, the HP printer driver does provide access to a number of features particular to this printer model. Most manufacturers include an installation CD that provide useful utilities ... albeit most are written for Windows. I would suggest checking out the Brother support site to see if they have Mac-specific drivers or utilities.

  • Share usb hard drive with a usb hub

    I have a USB Hub connect to the AEBS with a Dymo Label Writer and a WD USB drive connected. While I see the drive and the printers in the Airport Utility, I can't seem to connect to them from either WinXP Pro computer.
    Any idea what is wrong that I can't see them

    Hey guys, thank you all for your replies!
    Given actual price of hardware, I went for a totally different solution...
    I bough a used PC which I boosted with 4 GB of RAM... it's a intel dual core... and I plugged in a Terabyte SATA drive.
    It's much less expensive than a mac mini.
    Then I installed Ubuntu Server LTS and Samba for file sharing... FREE of course
    All that to get a very great file server that acts in PDC (security=domain) mode so it's totally great
    None of the NAS I reviewed gave me enough freedom for the file sharing management that I wanted, and the mac mini + leopard server solution where too expensive.
    Once my little company grows, imma get a Xserve fo sho but for now, this setup is the best for me
    once again, thank you for your replies

  • Using the integrated USB hub on my Thunderbolt Display causes troubles

    I just purchased a MacBook Air and a Thunderbolt Display. Unfortunately, when I connect USB plugs to the Displays buildin USB hub, I'm getting severed connections all the time (USB-Connection lost, Firewire-Connection lost, Ethernet-Connection lost...).
    I really loved the idea of not having to use external USB-hubs as this only clutters my desk - but the Displays internal hub cannot be used savely (I have a couple of hard drives connected via FW and USB to the Display - this has already resulted in data loss (fortunately I had a backup).
    As soon as I'm NOT using the Display's USB ports everything is fine (the Display's FireWire and Ethernet ports do not seem to cause any trouble).
    Anyone else seeing this?

    Plugging an additional USB hub into the integrated USB hub extends the problematic behavior even further.
    If I eject a thumb drive from a USB hub that's attached to the Thunderbolt display hub (for example), it will never recognize that thumb drive again, on any of the USB ports on the display or any additional hub connected to the display, until I reboot with no added USB hub, and then reconnect an empty hub, and then add devices one at a time.
    I've also noticed that while some devices drop off, some continue to show up in the system report, even when they have been properly ejected or disconnected. Refreshing the system report doesn't update with what's really going on...
    Weird... So since mountain lion, I don't disconnect any USB devices from the Thunderbolt display, unless I really, truly must.

  • Can a USB Keyboard/Barcode reader be used with the USB port on the CRio

    Is it possible to use a USB Keyboard or Barcode reader with the USB port on the CRio, I know you can use this port with a USB memory device, but what about other devices?
    I have a project that requires that all hardware elements be connected to the controller and use the HMI purely for display,
    anybody any ideas?? 

    Hi kmoyna,
    The standard CompactRIO range's USB host ports are not suitable for standard USB devices like keyboards or barcode readers - they are intended only for use of mass storage devices. From your description, it seems your project's requirements would be best met by the newer models, cRIO-9081 or cRIO-9082. These two units have Windows Embedded Standard 7 (WES7) and allow the direct connection of a monitor and standard USB devices. We now also have similar stand-alone CompactDAQ models running WES7 - cDAQ 9139.
    I would recommend calling into your local branch to discuss your project further with one of our engineers. If you're in the UK, it's 01635 523 545 - or view contact details for other branches.

  • 10.5.2 - Frozen Grey Boot Screen with Powered USB Hub -

    Hey guys I upgraded to 10.5.2 and after I did, I found my powered USB hub was causing a hanging grey screen when I turn the power on. Anyway does anyone know how to make it not lock up on a grey screen? If I unplug the hub it boots, but until I do it is an endless hanging grey screen. If it is a bug can you guys please fix because I find it really annoying to have to unplug and replug my hub every time I boot.

    Update: IT only happens when I plug my iPod into the hub that is plugged into my iMac. If I plug my iPod into the Macs USB directly it boots fine. Kinda a crappy bug or maybe a setting I need to change to be able to keep my iPod plugged into my powered usb hub when I boot so it doesn't hang.

  • Laptop not powering off with powered usb hub attached

    I have an external powered USB hub which I have attached to my G60 running Windows 7 Home Premium. When I try to shut down the G60 with the hub attached and powered on, the shutdown sequence goes through Logging Off to Shutting Down but never fully powers off. The power and wireless lights stay on and the fan continues to run.
    Is there a way around this apart from powering off the USB hub before shutdown?
    This question was solved.
    View Solution.

    Hi @Andrew_c51 ,
    I saw your post regarding the problems with your notebook not shutting down all the way when the powered USB hub is connected. It almost sounds like your notebook is going into sleep or hibernation. I would recommend contacting the manufacturers of the powered USB to see if there is a way of stopping this or just disconnect the hub.

  • MBP won't re-start with full USB hub

    Sometimes, when I choose Re-start from the Apple menu, my 2012 15" MacBook Pro w/Retina Display  just shuts down.
    I have done a PRM reset, and a CMS reset, and that didn’t solve it.
    I did an Apple Hardware Test, and it reported “No trouble found”.
    So I unplugged the the Satechi USB 3.0 hub and re-started, and it worked.
    Then I plugged the USB hub back in and removed all the peripherals from it, so its ports were empty, and Re-start worked.
    Then I started adding peripherals one by one, and discovered when they were all plugged in (USB modem, printer, label printer and scanner), that's when the problems occurred. Re-start would shut the computer down, I'd hear the start-up tone, and then it would sit there, black, with no Apple logo. As soon as I unplugged the USB hub, the Apple logo would appear and re-booting would finish.
    So my fix is to remove one peripheral (the USB modem) from the hub, and leave the hub plugged into the MBP. So far, it's working fine. Re-starts work great.
    Here's my first question: is having "too many" USB peripherals plugged in at once known to cause start-up or re-start problems?
    Second question: during all this testing, I found that the MBP's power button sometimes did not shut the MBP down until I held it for ten seconds. And sometimes (but not always) holding it down - even for ten seconds - would not start the MBP. I'd have to try 2, sometimes 3 times, to get it turned back on. This hasn't happened since I lightened the USB load, but might this be indicative of a power supply problem on the MBP, or is it likely related to the USB load?
    Thanks in advance for any advice or answers.

    Yes, having too many devices in the hub can definitely be a problem. The ports are not powered so they take power from the computer. Too many devices causes the computer to try and shut down the ports which it can't do properly in the middle of a restart. The total power the USB ports can draw is around 15 watts - 7.5 watts per port for two ports.

  • Boot problems with Belkin USB hub

    I can boot to my internal drive with the Belkin 7-port hub connected. But I can't boot to the System Start-Up Disk or to my external with the hub connected. And once I try, I can no longer boot to the internal until I disconnect the Belkin hub.
    I have heard their may be hub problems with the MBP and also with the Belkin hub. Any insight would be appreciated.

    These are interesting problems. I have a Belkin hub and have been having long boot times (sometimes 5 or 6 minutes) with a blank blue screen for most of the time. I get partial relief by disonnecting the hub. I also have an SD card reader attached to the hub (Memorex brand), so I'm going to try disconnecting that to see if it helps. One noteworthy thing is that these problems are new, whereas the Belkin hub and the Memorex SD card reader have been attached to my MBP for a long time.

  • Could I use a USB hub to connection both a printer and an external hard drive to the time capsule?

    I am planning on purchasing a new router.  The Time Capsule looks amazing.  However, I have Macs and PC's in my how.  So, I need to know if I can connect a printer (for all computers) and external hard drive (for the PC's) by way of a USB hub on the Time Capsule.  I've read that you can do this with the Air-Extreme.

    Couple of comments:
    You will need to use a powered USB hub to connect multiple devices to the USB port on the Time Capsule
    The hard drive for use with the PCs will not be compatible for use with the Time Capsule if it is currently formatted for Windows NTFS, which it likely may be if you have been using with the PCs.
    Same info applies to the AirPort Extreme.
    The following hard drive formats would be supported:
    Mac OS Extended (Journaled)
    MS DOS FAT32

  • Sun Ray 2 - Connecting to monitor with USB Hub issues

    Hi,
    We recently purchased 21 Sun Ray 2 devices and 21 Dell 1909W monitors with built in USB ports to go with them.
    This combination works great with 17 of the Sun Ray 2 devices, i.e. mouse and keyboard connected to USB ports on monitor then A to B USB cable running from Sun Ray 2 to Dell monitor.
    However, on 4 of the setups this combination fails to work, and after troubleshooting we identified neither the Sun Ray 2 or Dell monitors were faulty. Our support agents suggested since Dell could use a different USB hub 'engine' for their monitors (Even the same model of monitor) this may cause problems being picked up by the Sun Ray 2 devices.
    After trying out a box of spare A to B USB cables we had lying around spare, surprisingly 3 of the 4 before non working devices are now working. However, if the 'magic' leads were to be stolen etc we would have a problem again!
    Are there any sorts of firmware updates etc for the Sun Ray 2 devices that would mean we could get all the monitors working with the standard Dell provided A to B USB cables? At the moment the optical light on the mouse will 'blink' and then nothing else will happen (It does 'blink' on the working setups before getting full power).
    Many thanks :)

    no I tried with bro's iPod which have 4.x firmaware and it works fine. So I guess it's safe to assume this is problem because of firmware

  • MSI A55M-E33 problems with USB Hub

    When I boot with my USB Hub plugged in the screen will stay black and I get a 9C, 99, 92 or A2 error. Often after a few seconds this will disappear but sometimes it will just hang on 9C forever. Without the USB Hub plugged in it will boot straight into windows with no errors, but the internal buzzer will give one long beep and two short beeps.
    I used MSI live update 6 to upgrade my BIOS from W10 to W50. Inside the BIOS screen it is given as E7721AMS v32.5.
    The boot mode is Legacy + UEFI, and the boot order is:
    Boot 1: SSD (win 8.1 64 bit on here)
    2: DVD
    3: UEFI Hard Disk
    4: UEFI USB CD
    5: UEFI USB key
    etc
    My 2nd hard drive isn't listed as an option, though in another section of the BIOS (can't recall which) it is listed as being in a SATA port.
    USB devices are a wifi dongle, wireless keyboard & mouse receiver, and a D-Link DUB-H7 7 port usb hub (with 2 external hard drives attached).
    Any ideas what I can do? Would a different usb hub solve the problem?

    So I phoned a local computer repair shop, and he said it sounded like a faulty USB hub. He advised me to buy a PCI-E usb card and plug the devices directly into that. I was confident he wasn't trying to just sell me anything, as he didn't have these cards in stock and suggested buying one online.
    So I bought one of those cards and plugged the external HDD's directly into that. It has solved the problem with hanging on 9C (the beeping problem seems to have just disappeared by itself). Now I just momentarily get a 99 and A2 error then it boots directly into windows 8. Unfortunately the external drives won't appear for about 30 seconds, and also I can't use my wireless keyboard or mouse for the same amount of time.
    I'm fairly sure its not the fault of the drives. Today I've plugged them into two windows 7 laptops and booted those and the drives show up immediately. Same with the USB hub.
    Does it sound like a faulty motherboard? Or something not set correctly in the BIOS?

  • Inconsistant and unreliable TC when using USB hub

    I have a 500 GB Time Capsule, and have a Sitecom USB hub connected to it. On the USB hub are 2 external HDs, totalling to 3 partitions externally, plus the 500GB internal HD. I also connect either a Sandisk SD card reader or a Sandisk USB stick to it.
    Now, I just got the Time Capsule, gave it to my dad as a birthday present, and have just set the whole thing up. The thing is, it works well as a wireless router, but I cannot seem to get the USB connectivity working properly. When I try to access one of the USB-drives (be it a HD, card reader or USB stick), the thing crashes, the iMac freezes, and I have to restart both. The thing is, that it does not always does this. Sometimes it works fine, other times I have to enter my password and user name up to 3 times before it works, and even other times the TC just stares at me with a blank expression going "you want me to do WHAT NOW?!"
    In other words, it is unreliable with the USB hub. The hub has always worked fine while attached directly to the iMac, but because I want to be able to use the external HDs with my laptop as well, I have descided to get them in the network.
    Does anyone know what causes this behavior?

    Even the TC can work with external USB hub, it's not very reliable, and I would not recommend it. In theory, USB hub should be transparent, but I don't think the Apple engineers have ever fully tested it. I think when you have two or more drives connected to the TC, TC has problem allocate system resources correctly internally.
    My recommendation for the external USB drive configuration is to have just ONE single drive, with ONE single partition, either FAT or HFS+. USB hub should be fine but restrict it to just one drive, use HUB hub for printer seems to be fine, but then you are only allowed one printer per TC anyway.
