Recognizing two USB ports in GarageBand

I've connected two USB mics to GarageBand and created an aggregate device with the two mics in Audio MIDI. The issue is GarageBand does not seem to pick up both USB ports. I need both mics for a two-person podcast setup.

So, basically, GB is only letting you choose one of your two mics for all of your tracks and the other just doesn't appear as an option when choosing a track input?

  • Solution to only TWO USB ports, please

    I should have paid more attention when I bought my Mac. I didn't realize there were only TWO USB ports on board. My job requires me to be mobile, and on any given day, I could be using up to 10 USB ports. I know they make hubs, one of which I've tried, but it didn't work. Does anyone recommend a particular brand of hub that's RELIABLE and can handle both input and output?
    I'm stunned that Apple would have just 2 USB ports. My old Dell had 4, and if I remember right, I could have specified even more when they were building it.

    Yes, that's the ExpressCard/34 port (labeled in this linked image). The ExpressCard port also be used for media card readers, WAN (wireless broadband) cards, etc. Good for a USB expansion hub because it's a small form factor and won't take up one of the two existing USB ports.

  • Ex-80gb PS3 hdd - in enclosure.. need two usb ports?

    Have got a 'Omata Mobile HD' enclosure.
    Have installed the 80gb formatted hitachi drive that was in my PS3 into it.
    PLugged it into powerbook usb port... disc utility doesnt recognise it... read instructions again from Omata, all in pigeon english - just talks about windows install etc.. .google search later reveals that it needs two usb ports - one for power, one for data - is this true? Does this go for all enclosures?
    i would need to then buy a usb extendor as the usb ports are on opposite sides of the pbg4.
    Are there any enclosures that can run a 80gb off one usb port? It also has DC 5V/1A on the enclosure are these quite common?

    Hi, Steve. Given the inconvenience of connecting a dual-USB "Y" cable to your Powerbook, the drawbacks of USB2 compared to FireWire for use with any Powerbook (USB is non-bootable on all PPC Macs and slower than FW 400, never mind FW 800), and the very low cost of your Omata enclosure, I recommend simply replacing it with a FW enclosure. Save the Omata one for use with your next Mac, which will be Intel-powered and USB-bootable, and won't have the limited USB bus power problem that afflicts all Powerbook G4s. Most bus-powered FW enclosures are bootable and have no trouble getting enough juice from Powerbooks, unlike nearly all USB2 enclosures. Get one that has the Oxford 911+ FW bridge chipset in it; that's far and away the most reliable bridge.

  • Two USB ports - Same bus?

    Hi folks. I recently purchased a new 2013 MacBook air due to the two USB ports. When I plug two USB devices into it, it appears that they are being placed under the same USB 3.0 Hi-Speed Bus. (Getting this information from the System Report).
    The system report shows that there is one USB 3.0 Hi-Speed Bus, and one USB 3.0 SuperSpeed Bus. I really need each device to be on it's own USB bus. Is this possible?

    I'm saying that it appears that there is only a single USB bus for the MacBook Air, while all of my other laptops generally have one bus per USB port.
    On the Air, both ports go to the same USB host controller. On my MBP there are two USB busses, each one going to a different host controller. I have never seen a laptop with two usb ports going to the same host controller, this is just very unexpected is all.

  • Aluminum Keyboard Sometimes Not Recognized By USB Port

    I have an Aluminum wired keyboard that occasionally isn't detected by my Macbook in both Windows XP (Boot Camp) and Leopard. This is an exchanged one because the first one also behaved this way. I'm not using the extension cable. I have a USB wireless mouse plugged into one of the keyboard's USB ports and a flash drive. When the keyboard isn't detected, the mouse doesn't work (no lights on the receiver, can't connect), but the flash drive gets recognized. I've also had the keyboard not be detected without the flash drive so I know that it isn't the issue.
    When it isn't detected I have to disconnect and reconnect the keyboard multiple times until it randomly starts working. Once it works, it doesn't stop working, though after going to sleep it occasionally disconnects itself on startup. All the function keys work properly and there's no updates available...is there anything I can do about this?

    I've seen the very same problem. In my case I have a wired Mighty Mouse attached to one of the USB ports on the aluminum keyboard. Every time I plug it in -- not recognized first time. Second time -- success. Highly annoying.
    Unfortunately I don't have a solution for the problem.

  • Ipod Touch not recognized by USB port on my new radio! PLEASE help?!?!?

    Ok, so I just bought a new radio for my car so I can listen to my ipod touch 2nd gen (with the latest 3.0 software) through my speakers. Ok, that's all great, but the problem is that when I connect my ipod touch through the USB port on my new radio, it reads "device error"...
    My radio is an Alpine CDE-102. It does have an AUX input, and I can easily get a cable to fix this problem... but I'm wondering why my ipod touch doesn't show up through the USB?!?! And I don't know how AUX input sounds compared to USB input (probably less quality than the USB...)
    So, can you help me? I've also connected my ipod touch to my xbox 360 and it shows up as a camera - can't play music... all part of the same problem I guess...
    This is a SERIOUSLY annoying problem especially since I just dropped some cash on the new radio which might not even WORK!!! AHHHHH! A problem with the USB cable? Problem with the Ipod? Problem with the stereo? I'm not quite sure what to think...

    That is the ONLY cable that will work with that radio:
    http://www.alpine-usa.com/US-en/products/product.php?model=CDE-102&view=Specs
    From reading the manual for your iPod I'm pretty certain the connector is on the rear of your unit.
    You can connect an Auxiliary cable to the headphone out on your Touch to the AUX in on the radio but you will have to control everything with the iPod and it will not charge.
    The cable is $30, why don't you ask how much they would charge you to install it?

  • Re: 2 two usb ports on left side of my hp pavilion g6 2230 is not working

    Hi,
    Is your notebook still in warranty?  Warranty status check webpage
    If some ports work and others do not, then it is quite likely that the issue is hardware related. Replacing the system board would be required to resolve the issue. If the issue were operating system or driver related, then no usb ports would work.
    As a workaround you can use a powered external usb hub.  If you use an unpowered hub then you are quite likely to kill another port. You must have used a usb device that drew more current (in µA).  The same thing happens to motherboards in PCs, so don't feel lonely.  You can see what I mean about the power limits of usb ports in the following image. Go into the device manager and check your usb ports power availability and power required.
    Best regards,

    Dear Sir,
    I read your answer. You said that if one USB port is working, others should also work. Thus this could be hardware related problem.
    Fortunately I have ubuntu also installed as second operating system.
    The left usb ports are working on the Ubuntu system. Thus we can conclude that hardware is perfect.
    Now with above reference, can you please guide on how can the left USB ports can also funtion?

  • My Ipod Shuffle has fried two USB ports in my computer

    Hi!
    I have been reading through all the forums, but I have not seen anything written about Shuffles burning the USB ports.
    My Ipod shuffle was connected and suddenly, I heard an explosion and my computer when black. I went and changed the ipod at the store, got another one, and the same thing happened with another USB port.
    Now, I change the USB dock, but still the light in the Ipod won't change to green.
    Please, let me know.
    Regards,

    Apple cannot fix your PC... the warrenty for the PC is with Dell so only they (or an authorized repair centre) can repair it. Apple will repair your shuffle should it be faulty.
    I would recommend trying a re-installation of Windows and if that doesn't work, contact dell for the repair.

  • HP G4-2275dx left two usb ports not working after OS install.

    Hi all.
    I had to remove my windows 8(Upgraded to Pro before) install due to compatibility with certain programs and I was not very satisfied with the results.
    So I had an extra cd key for windows 7 x64 home premium.
    Everything went smooth.
    I had all my drivers installed.
    I installed Direct X also.
    But when I tried to use my tutle beach headset it would not install the driver for the headset or even make the sound when a device is mounted.
    So I checked device manager and I saw three yellow excelemation errors.
    two were "Universal Serial Bus(USB) controller"
    one was "SM bus controller"
    I have installed the catalyst drivers multiple times but no dice.
    Any help will be appreciated.
    Happy Holidays.

  • 9300 not recognized at the USB port

    Hi all,
    please look at this issue..
    http://supportforums.blackberry.com/t5/BlackBerry-Curve/curve-9300-3G-not-recognized-at-USB-Port/td-...
    Thx

    My iphone 4, when plugged into my windows xp laptop, wasn't recognised. "USB Device Not Recognised". I was obviously concerned I had just bought a broken iPhone 4...
    However, I used a different Apple USB cable and it worked first time on the same windows xp laptop and in the same USB port. The cables look different, the first one had a rounded USB head cover, maybe it was a iPod one (I did buy the phone from eBay). The second, and working cable, has a square USB head cover. I don't know if that is important or not but hopefully the same solution will work for you.
    If not, there is a video here that suggests an alternative solution.

  • Independent recognition of two usb microphones (same make and model)

    Hi Folks,
    The issue described here was already nicely described in a different post during a response to a different question. I reproduce it here, since it seems to warrant some independent attention. The original post was from "Points East" and the link is:
    http://discussions.apple.com/thread.jspa?messageID=13127891&#13127891
    Here is what was posted by "Points East":
    "I'm trying to use two Blue Snowball usb mics for audio input to GarageBand. When I connect them I can see both in the System Profiler (one on each hub with different location ID's) but when I go to the Audio Midi Setup utility to create an Aggregate Device I only see one listed."
    I, too, am having this same issue. Let me add more detail:
    * I can plug the two BLUE Snowball microphones either into the two USB ports on my MacBook (running 10.6.7) or into two ports on a powered USB hub, which is then plugged into 1 of my USB ports on my MacBook
    * I can see these listed as two separate USB devices in the System Profiler
    * However, in "System Preferences"->"Sound" only one of the two microphones appears listed as a USB device and only one (the first one plugged in) is responsive when exposed to sound (tapping on the mic).
    * Also, in the "Audio MIDI Setup" the microphone model is only listed once and seems to correspond only to one of the two plugged in microphones
    * Separately plugging in one mic at a time shows that both independently work find and record sound. It is only when they are plugged in at the same time that one of them doesn't get listed in "System Preferences"->"Sound" or in "Audio MIDI Setup" and thus I cannot actually use both mics to record.
    Is anyone else having this problem, and if so, has anyone either solved it or have some idea about where to begin testing?
    Regards,
    Steve

    Just as further information about this issue, here is what appears for the two microphones in the System Profiler:

  • Toshiba M70 USB ports issues...

    Hi all, i have an m70 and all 4 USB ports are acting weird, my usb card reader, optical mouse, and any other thing i put in any of the ports they intermittantly work. The mouse and reader will light up but do nuthing but other times light up and work. Not sure what this is or if maybe its common? any input would be greatly appreciated!!!! thanks!!!

    I have a similar problem with my Satellite L645D-S4033.  I just got it yesterday and the two USB ports on the left work fine but the one on the right has a problem.  When I plug a device in it says the device is not recognized.  However, if I have the device plugged in when I start/restart the computer it works fine.  I'm currently waiting for a call back from Toshiba Tech Support.  Right now I'm doing a system recovery to see if that does anything.

  • Help with USB ports

    Hello, I have a Toshiba Satellite L655D-S5159RD.  When I bought my laptop a few months ago it came with 3 USB ports and basically ever since I got it, the two USB ports on the right side have not worked properly.  For example I can plug something that requires power like a fan and it works but things that work perfectly on other comuters like a wireless mouse or external hard drive just do not get recognized by my laptop.  Any help on this would be appreciated.

    Go into the Bios and click on the Advanced tab. There should be a setting for the USB Legacy Emulation mode. By default, it is usually enabled. The USB Legacy Mode is for older USB devices like keyboards and disk drives. Disable the USB Legacy mode and try again. There may be a problem with some of the newer USB devices like hard drives and wireless mice with the USB Legacy mode enabled.

  • Just one USB port on MacBook Pro 15"

    Both USB ports are on the left side, right next to each other.
    Maybe you have too many things plunged in and you can't see it or something is covering it up. Reminds me of this:
