  • How to stop/disconnect USB device on OSX?

    How do I manually stop a USB device that I don't want the OS to recognize or run?
    On "About this Mac > More info" page, my Dell Axim X51v Pocket PC is listed as a USB device. I'm having problems using the Parallel Desktop running Windows XP to sync to the Axim because Parallel reports that "USB device you are trying to connect to the virtual machine is being sed by another process." Wait 5-10 seconds, then try to connect the device again. If this does not help, find the application that blocked up the device and disconnect it manually."
    AFAIK, nothing on my Mac is using the Axim right now, I have even disabled "Missing sync for Windows Mobile" and stopped it from loading so it must be the Mac OS not releasing the USB link so my Windows XP within Parallel is not able to pick up the Axim right now.
    In Windows, there's a "Remove Hardware" option. But I can't find this on OSX after digging around for half an hour, I think I'll get much better advice here, so I really look forward to your help.

    You wrote: "But I don't see the device as "mounted" on the desktop, or in Finder."1. In the Finder > Preferences > General tab, is the "Show on Desktop" option for CDs, DVDs, and iPods selected? If not, select that option and see if it appears on the desktop.
    2. Is it shown in the Finder Siderbar?
    Good luck!

  • How to blacklist a usb device in BSD?

    I am having trouble communicating with a usb device while running Virtualbox on my iMac (Lion).  Virtualbox is virtualization software which lets me run Windows XP as a guest OS.  I am trying to run Palm Desktop for Windows on the virtual computer and I have trouble getting the USB connected Palm device to sync to the Windows application.  It turns out the Palm device's use of the USB protocol is not quite conventional and so the virtual OS has trouble capturing it and presenting it to the Windows application.
    Others who run Virtualbox under linux have seen this same problem with Palm devices and have found a workaround by disabling the host linux USB driver so that the Virtualbox application has unfettered access to it.  This process is called "blacklisting" a USB device under linux, and involves editing the "/etc/modprobe.d/blacklist.conf" linux config file.  My question is can I perform a similar operation in MacOS?  The BSD I/O subsystem is different enough from linux to prevent me from knowing where to go in OSX to do a similar modification.

    I'm having the same problem.  I can't get OS X to ignore an SPI digital logic device (MCP2210) that I want to run from my Windows XP Virtual Box in order to control an experiment.   Virtual Box sees it but it's grayed out under the list of USB devices to mount in Windows XP, and I don't know how to get the Max OS X to released/unmount/ignore/blacklist it.

  • Need informatio​n on how to comunicate with USB devices

    I have an aquisition unit that connects to the computer trhough a USB port. Does anyone knows how to comunicate usb devices with labview using a Universal Serial Bus (USB)?

    Sorry for digging up old threads, but it seemed most relevent, and I always figure it's best to add onto old then start new. For ease of the next persons search.
    So anywho, My first question is... I assume it is not necessary to open and close VISA sessions to USB ports, right?
    I am having an issue where my device doesn't like to work unless a specific series of events take place... very unlike USB Devices in my experience. For instance, if you have the said device plugged in, and you turn it on, then open labview. It will spit out garbage. If you close labview, do nothing else, and open labview up... it will spit out the same garbage.  ( by garbage i mean a series of y's with dots over it, and odd looking p's ... you know the kind of letters you get by pressing alt+###... i think in hex it winds up spitting out something like FF EF FF FF FF EF EF ) .... now, if from this current state, I unplug the USB and plug it back into the device, it will finally start to communicate properly.
    Im curious why either labview or the computer itself are not recognizing the device on the USB port properly unless it is unplugged and then plugged back in. Ive tried to do reading on USB, and got all sorts of interesting tid bits of somewhat useless information.  Im trying to determine if this is something I am not doing in labview, or if this device should have a driver to register with windows, or what exactly the issue is...  Just a little background, I do explicitly know all the individual commands to this device so it is not an issue to communicate with it directly through visa...
    Thought some of you might have insight or some similar USB experiences....

  • How to debug adding usb device

    When I add my new Iomega Helium USB HD to my Macbook Pro running 10.6.8, the screen and keyboard all freeze. There laptop has to be rebooted. It does this when I do it standalone and when I use external screen, keyboard and hub.
    It is a problem with my setup because the drive works fine will all of the other Windows and Mac machines I have.
    The cause was the installation of the Iomega software (why did I ever trust Iomega software?) as I only installed it on my macbook pro.
    Can I run some diagnostics/debug to trace the insertion of the USB device to see where it is going wrong? I have manually uninstalled the software but I am convinced I have missed something.
    I have a complete clone backup from before the installation but don't want to lose other changes (like email etc) since that day, although I am happy to restore specific files.
    Thanks

    And it used to be fine until I installed the Iomega software.
    Iomega software, i.e., software to use an external drive.  Never a good thing (I guess you are finding that out).
    I always recommened external enlosures which are dumb boxes, i.e., their only purpose in life is to allow you to communicate with the drive they enclose.   Additional software only gets in the way and you shouldn't need it.
    If that box was running fine without their software what prompted you to add it?   And why can't you uninstall it?

  • USB Devices lock-up iMac 2011

    2011 iMac 3.4Ghz i7 SSD+2TB 2GB AMD 16GB Corsair RAM
    I noticed I was experiencing random lock-ups and freezes during the first few weeks of owning the iMac.
    I went down the line of changes I made to the system.
    RAM Upgrade, software installs.
    I went with a bare OS, stock memory, still experiencing lock-ups.
    added everything back, still experiencing lock-ups.
    kept everything unplugged for two weeks, played itunes movies in quicktime on loops (10 total, 5 form the ssd and 5 from the hdd) to see if one or the other would crash the system. Two weeks straight no crash.
    Plugged my iPhone in to sync and update, after a few hours over 8hours) i came back to the system froze & locked. no mouse movement or keyboard input (caps lock key wont turn on and the seconds in the top clock were stuck).
    hard restarted, left it run for a week nothing, plugged in my apple wired keyboard, the next day hard freeze/lock-up.
    this was repeated with each usb port, within a few hours to a few days the system lock-up freeze with any usb devices plugged in.
    it would not do this with FIreWire devices or audio cable or ethernet cable attached just USB.
    is there any way to resolve this without getting the logic board replaced? or is this a firmware/software issue?
    other than that the system is amazingly fast and one of the best.

    This is the error protocol I get in Console:

  • How to disconnect a USB device that auto-connects to my iMac

    I have a third-party device that gathers medical data that can be uploaded to my computer via USB. Now, however, I want to upload it to a web-based application application that runs only on Windows. I run Windows 7 on a virtual machine via Parallels 7. The problem is that when I plug the medical monitoring device into the USB port it automatically connects to the Mac, and I cannot see it from the Windows desktop. Plugging it in no longer gives me the option of connecting to the Mac or the PC. (I think I did an "Alt [right click]" the first time I connected via the USB cable.) So, how can I now force that auto-connect to disconnect? Thanks.

    Hi Bob, I remember doing something like that...
    On the Mac side eject it without removing it, then on the Win/Parallels side look for that USB thing setting/add device or whatever.

  • How to add and configure a usb device driver in SRSS for Sunray?

    Dear Sir,
    If I want to use a usb device on Sunray 2 (the usb device is plugged into Sunray's usb port), and I have been developed a usb driver on Solaris 10. Can I install the same driver in SRSS host to active the usb device in Sunray? If it can, how do I configure SRSS and where is the location of SRSS drivers? Can I use add_drv similar command to add my driver to SRSS?
    The second question is when I plug-in a usb device to Sunray, can I see device information (VID, PID, and so on) in any log file or by any command as "prtconf -v" on Solaris?
    Thank you very much.
    Best Regards,
    Steven

    What sort of USB device do you want to use ?
    The peripherals chapter in the SRSS admin guide tells you how to use supported USB devices.
    http://docs.sun.com/source/819-2384/dev.html
    Drivers written for Solaris devices will not work with Sun Ray devices. If you want to write a device driver for Sun Ray, it is recommended you use libusb for a userland driver. See libusb notes on same chapter mentioned above.
    There is currently no SRSS utility to list Sun Ray device parameters like prtconf does.
    You could write a libusb application to do this, or use the test program described here:
    http://libusb.sourceforge.net/doc/examples.html

  • I want to reactivate the USB device

    Bonjour, Hi ,
           J'ai un Macbook pro sur OS X 10.9.4, processeur 2,5 GHz, intel core 5.  Mon port USB a été désactivé en me disant que l'appareil que j'avais connecté ( un I-phone) prenait trop d'énergie. Comment puis-je le réactiver?
    How to reactivate the USB device?

    USB is used by the display for brightness and other functions, in addition to being a hub. The USB circuitry is part of the main board, and is not upgradable. Connect a USB 2.0 hub to the computer if you need more USB 2.0 ports.

  • Identifying attached USB devices

    Is there some way to get a list of attached USB devices and their speed (i.e. USB 1.1, USB 2.0)?
     20" Intel iMac (2.0GB RAM, 500GB HD + 1.5TB external, 20" Cineama Display)   Mac OS X (10.4.7)   All tools, no talent!

    I guess the manuals would if I could find them I'm pretty sure the hubs I've added are all 2.0. In the Window's world, if you plug a USB 1.1 device and USB 2.0 device in the same hub it warns you that the faster device may not work at the faster speed. I've found this to be true. I've been getting some strange results with my USB devices on the iMac so figure it's time to separate the 1.1 and 2.0 devices to different hubs. We shall see.

  • Was told a USB device would create a PDF automatically from the data contained within when plugged into my USB port. Doesn't seem to work. How does this work and how can I fix the device I received?

    Acrobat is not on the USB device - only Adobe Reader needed on the PC. How does this work? How can I fix this device if at all?

    You need to ask the people who sold it to you. Doesn't sound like it has anything to do with Reader.
    However, you should be wary of devices that automatically try to open files when plugged in. They can also infect your computers with all kinds of viruses or malware.

  • How do I use more than one USB device with Airport Extreme?

    I would like to plug a shared hard drive into my new airport extreme and still be able to plug in a shared printer as well. How am I supposed to do this with only one USB port. Do I use a USB hub???
    Is it possible to connect a hard drive using one of the ethernet ports?

    To use multiple USB devices you would use a powered USB hub.
    You can connect a hard drive to one of the Ethernet ports providing the hard drive is a NAS and supports Ethernet connections. In that situation the NAS hard drive is just like any other Ethernet client and the AirPort Extreme base station (AEBS) does not handle the file sharing services. The drive itself would provide the file sharing services.

  • How can I access an unsupported usb device that's seen by system profiler

    is there a way to access an unsupported usb device? my parents bought my daughter a cheap and easy to use digital camera and I am looking for a way to access the photos. the camera's manual mentions that there is no mac driver and there are no plans to develop one. I plug it in anyways in the event the system / Iphoto recognizes this, But I get nothing on the desktop as in a generic disk image icon. I open system profiler and My G4 knows the camera is plugged in. If this interface between the two is recognized how can I access the camera?
    does a driver have to be written to allow access? I saw a usb dev kit on version tracker but I have no clue as to how to write a driver. I could get a flash card reader but I was hoping that there may be some back door or an app somewhere to allow me to get the photos off the camera.
    thanks!!!

    Hi, Israel.
    You wrote: " I plug it in anyways in the event the system / Iphoto recognizes this"See if Image Capture recognizes the camera. Launch Image Capture, which is in the Macintosh HD > Applications folder.
    Otherwise, you're probably going to have to go the route of using a card reader. While the connection may be USB, they may be using some non-standard implementation that requires a driver.
    Writing drivers is not something you'd want to even attempt since you didn't create the hardware!
    Good luck!
