Using USB 2.0 devices

Hi, I've got an eMac 1 GHz with Firewire but only USB 1.1. I would like to use a Miglia TV USB-key to watch numeric-TV but it doesn't want to work, because it needs USB 2.0.
So one question : would it be possible to use the firewire port through an USB to Firewire cable, or a Firewire Hub with USB ports such as this one :

Thanks

Sadly, no. Combo USB/Firewire hubs are separate USB and Firewire hubs in the same chassis with the same power supply; there's no data conversion from one to the other. There have been misleading advertisements for "USB/Firewire cables"; read the fine print, and those things are double-headed cables that can be used with USB or Firewire, but not both at the same time. There reamins as far as anyone herabouts knows no way to adapt Firewire to USB 2.0; if there were, owners of pre-USB 2.0 Macs would be snapping such devices up to use with current generation iPods.

  • Help needed to use USB 9481 relay device

    I am new to LabVIEW so any help would be appreciated.
    I am attempting to start and stop an instrument with the USB-9481 relay device. On my instrument, connecting pins 1 and 2 will start the machine, and connecting pins 4 and 5 will stop the machine. How do I program LabVIEW to connect pins 1 and 2, wait a determined time, disconnect the connection, and then connect pins 4 and 5? No power needs to be supplied since the 12V is already being supplied by pins 2 and 4.
    Thanks so much.

    Hi Josh, No problem.  I took a look in the NI 9481 Operating Instructions and found this information to be quite useful:
    As far as the DAQ Assistant goes, you can only have 1 DAQ Assistant per device, so you will need to add channels to the DAQ Assistant by pressing the '+' button near the top left (just below the Play button). This device is pretty simple, and I'm sure you'll be using it in no time.

  • What is the disadvantage of using USB 3.0 device through USB 2.0 port?

    My mac only has USB 2.0 but I'm told to use an external drive with USB 3.0 for better speed. Do I forfeit the 3.0 speed by plugging into a 2.0 port? Even though the 3.0 device is compatible with 2.0, is there a disadvantage?

    Thanks for the reply. So basically, if I want to fully utilize the speeds available for USB 3.0 devices, I need a new mac, right? Is there an adapter or workaround? I have memory-intensive sound libraries for use with Logic that are recommended to be stored/run from a SSD or 7200 rpm USB 3.0 drive, so I'm trying to determine if it's worth it to fork out the cash for an expensive external drive, or if it doesn't gain me anything anyways because I'm limited by the USB 2.0 ports on my iMac.

  • Why does wifi quit on mac mini when using usb 3.0 device?

    I've got a brand new Mac Mini with Yosemite 10.10.3 and I've added an external USB 3.0 SSD. When booting from the SSD I lose wifi connectivity. If i turn off the SSD and boot from the internal disk wifi is fine. Has anyone else had a similar problem?

    That is a known problem with USB 3

  • Using USB 6341 device for frequency generation but level is droped when conect

    i am using USB-6341 Daq Device for frequency generation. The desired frequency is generated correctly but when i connect to other device the voltage level i means the Peak to Peak voltage of the frequency dropped to 0.6, 1 Volt and also the frequency fluctuated. As I disconnect it from the load or the device the frequency becomes constant and peak to peak voltage becomes 5.
    Please some help me to resolve my problem.
    Thanks
    Best Regards

    Solved!
    Go to Solution.

    Hi Nasib,
    I just wanted to clarify a few more things. Can you answer the following questions?
    What frequency are you trying to generate?
    When there is no load connected do you see the desired frequency?
    When the load is connected, does the frequency always change to the same value or does it fluctuate within a certain range? If it fluctuates, what is the range?
    Also, what microcontroller are you using?
    Can you provide any images?

  • Connecting Agilent DSO3062A Oscilloscope with LabVIEW using USB

    I am trying to connect Agilent DSO3062A Oscilloscope with LabVIEW using USB but the device is not recognized by MAX. I have installed the drivers for scope and it works fine with the scope software. The problem is LabVIEW dosen't recognize the scope. Please tell me the procedure of setting up the scope with LabVIEW 8.2. I am using Windows XP.

    Hi there,
    I think the issue is that the DSO3062A will not be recognized by LabView as a GPIB instrument through the USB connection. If you check out the 3000 series manual (http://cp.literature.agilent.com/litweb/pdf/D3000-97016.pdf) you'll notice on page 8 it says you can't use the USB for programming, it can only be used with their scope software. You need the N2861 module installed on the back to connect via GPIB, and then a GPIB interface to your computer. I hope that helps.

  • Using USB storage devices very slow in SL

    I have two MAC's and use Entourage on both, in order to keep my Microsoft Data Base sync's I have it on a removable storage device which I move from MAc to Mac. Since updating to 10.6.1(SL) Entourage has slowed down to a snails pace and I can only assume that SL is doing something different in handling the USB external storage devices .
    Very disappointing and frustrating .....Apple not a good move
    Anyone else having problems

  • Using USB-8451, and AD7747 from Analog Devices to measure capacitance and convert the capacitance to digital output

    Hello,
    I am new to LabView and data aqusition. I have LabView 8.5.1 installed on my laptop, and I studied the Getting Started document of LabView, except the data aqusition chapter.
    I have microfabricated a differential capacitive sensor, and now I want to test the capabilities of my sensor.
    After asking NI engineers, I have been suggested to use USB-8451 with AD7747 (24-Bit Capacitance-to-Digital Converter) from Analog Devices because AD7747 has I2C serial interface.
    I have ordered USB-8451, AD7747, and Evaluation Board for AD7747. And I am waiting for them.
    Are there any suggestions about how to connect my differential capacitive sensor to AD7747, and eventually to USB-8451?
    You may want to know some further information to answer my question:
    *The sensor is similar to the sensor on pages 501, 514, and 515 of "Microsystem Design" book from author Stephen D. Senturia.
    *The datasheet for AD7747 can be reached from this link: http://www.analog.com/static/imported-files/data_sheets/AD7747.pdf
    *My purpose is to make a very precise and accurate "displacement measurement micodevice" by using "the change in the capacitance" during the motion of the mobile fingers of the sensor.
    As an initial challenge for myself, I will feel satisfied if I can measure the capacitance change in my sensor when I apply an external mechanical disturbance to my sensor. For example, there must be a change in capacitance if I just swing my hand from top of the sensor region.
    I am looking forward for your reply,
    Thanks in advance,
    Sincerely,
    sriverfxtr

  • Mixed message lengths on CAN Bus using USB-8473 Device

    I am attempting to use the Frame API functions for LabVIEW
    and send both 11-bit and 29-bit headers over a bus that uses both address lengths.  I am currently successfully sending 11-bit
    packets but the 29-bit packets are having their addressing truncated to the 11-bit
    length when put on the bus.   
    As far as I can see I should have to set the standard
    comparator to 0xCFFFFFFFF and then send messages.  I am using a NI USB-8473 CAN Device for doing
    this.  Is there anything else I need to
    change for extended addressing?

    You need to OR your Extended ID with the 0x20000000 before giving it to the NCwriteNet.vi.
    This is the way that the underlying CAN driver and hardware know that is it an extended ID you are trying to send.
    The ID on the CAN bus will NOT have the ORed ID but only your ID. The driver/hardware filter the 0x20000000 from the ID.
    This is the same for reading an extended ID on the CAN bus. 
    Before using the ArbitrationId, you need to AND the ArbitrationId with 0x1FFFFFFF to filter the extended flag out.

    Easiest on Mac OS X 10.7 is to use this button:

    In Mac OS X v10.7, the $HOME/Library folder is a hidden folder.
    Open Finder and use one of these:
    * Go > Go To Folder (Shift-Command-G) and in the dialog type: ~/Library
