• USB drive will not appear in the finder, but is OK in disk utility

  My "music backup" external USB 1 TB SSD showed in the Finder, until a few days ago, when he disappeared. I tried dismantling and Assembly of the command line. The said command-line editing is successful, but I still don't see the drive in Finder.

  If I go into disk utility "First aid" reports no problem. The drive is formatted for OS X.  If I right click and say "Open in the Finder" I can see all the folders and even drag in the sidebar where they work, even after a reboot. I can't see the drive at a higher level.

  How can I fix it? I guess a solution would be to create a folder called "Music disc" and then move all files on the disc in it and then put it on the sidebar, but it seems silly. How can I get my hard drive appears again in the finder.

  PS Si I use a third-party file manager, such as ordering a PRO, the USB drive is available for selection in the drop-down list of disks attached.

  Help!

  The Finder, choose utilities go to menu, open the Script Editor and run:

  the shell script ' chflags nohidden ' / Volumes/VolumeName /'.

  put the name of the drive where is VolumeName.

• I have two devices gpib-usb-hs; two of them work in MAX, but will only work in labview, help please?

  Hello

  For my application, I need to communicate with two instruments by using both devices gpib-usb-hs. I use Windows XP, Labview 6.1, MAX 5.1 version and NI488.2 version 2.42. I checked and this ni488.2 driver should be compatible with my devices gpib-usb-hs and my versions of windows and labview. I also tried versions older and more recent NI488.2 without success.

  I can communicate with my instruments properly in MAX, tell me that the devices themselves are functional. When I try to connect with my instruments using labview (using the example of gpib of labview), only devices gpib-usb-hs communicates with success. The other device returns the EDVR error: connection to the device or driver error.

  I don't really know where to go from here. The only thing I found strange was that the gpib-usb-hs work was has an alias name assigned visa while the unworking device does not. I tried to give him an alias name, but this did not help.

  Any suggestions would be greatly appreciated.

  There are many free tutorials on GPIB. It should explain how the various instruments can be connected to a single controller.

  That being said, even if it's unnecessary, you should have no problem with multiple controllers on the same pc. The two being connected, they pass all the tests in MAX? You are using an old driver and seem to have tried several different versions. I suspect a driver issue, and I advise you to uninstall all the drivers GPIB and VISA and then start again. But not all necessary can be done to satisfy your curiosity.

• GPIB-USB-HS Windows Server 2003 driver available?

  I tried to install the GPIB-USB-HS device on our system of Windows Server 2003 R2 Standard 32 - Bit (German) with the last driver NI488.2 3.0 package.

  But the driver seems to be evil. After restarting Windows comes up with an error and event poster of the errors of several Viewer too:

  -The "nipxirmk" service failed to start due to the following error: the specified driver is invalid

  I think that the latest package isn't compatible Win Server 2003 but that it is announced at ni.com.

  Is it possible to install GPIB-USB-HS on a Win 2003 Server machine?

  Thanks for your help

  Windows Server 2003 32-bit R2 enables PAE by default ("physical address Extension") mode for addressing memory above the 4 GB limit.  National Instruments supports this operating system, it does not address memory above the 4 GB limit by using EAP setting and many pilots OR will fail to load if this setting is enabled.  (Note that your computer may intuitively put some of your memory above the 4 GB limit, even if you only have 4 GB of RAM).

  On Windows Server 2003, you can disable the EAP or prevent Windows to use addresses beyond 4 GB, which allows loading the drivers EITHER.  Please see KB 54D9I6M6: OR software failure when PAE (physical address Extension) is activated on Windows operat... for more information.

  2. If I plug any USB keyboard or a Bluetooth keyboard on it - it does not recognize.

  However, the Bureau will recognize any wired (USB) or mouse wireless (bluetooth) connected.

  It baffles me that the bureau will recognize a usb or bluetooth mouse mouse - but that it will not recognize the bluetooth keyboard or a usb keyboard.

  I tried many things

  1. connect the USB and Bluetooth keyboards in my laptop and check that they work properly. -They are.

  2. I tried using different USB ports on the desktop. He has not made a difference.

  3. my computer allows you to access its bios using F8 - I checked that my material was grateful the Generic USB keyboard before loading Windows. (I could select F8 and bring up the desktop in mode of Bios Configuration).

  4. I tried to start Windows in safe mode. That did not help at all.

• GPIB-USB-HS Windows drivers only

  I use a GPIB-USB-HS USB GPIB adapter for laboratory automation and need to install drivers for devices on a certain number of the PC lab.  All I need are windows drivers and eventually DLL managed, although I would rather deploy DLLs and my applications.  All my software automation runs on the CLR and not of labview.

  My question:

  How can I get only the drivers for this device?  The only download that I can find on NI.com ( http://joule.ni.com/nidu/cds/view/p/id/2129/lang/en ) installs almost 400 MB of software which should really go on my lab PCs.  In addition, the size of the package makes deployment and maintenance a bit unmanageable to me.

  Best regards

  Peter Baughman

  Hi Peter,.

  Unfortunately, there is currently no 'activity' version of the GPIB driver, so the link you provided is the right driver which should be installed on each computer that will run your GPIB software. Without having to install this driver, the GPIB-USB-HS will not be recognized by the client computers.

  Best,

• Satellite Pro L10 - USB port will not recognize devices

  Hello

  I got a L10 for 18 months. Under the guarantee, I got a replacement motherboard mounted. Everything has been ok so far. A USB port will not recognize devices, a port is ok, but randomly turns off a device attached to it and comes up with the message "USB device not recognized". The third port is ok all the time.

  Any solutions or suggestions?

  Post edited by: caddy

  I guess there is not enough power on the USB ports and external devices may not work correctly. It is not easy to say why this happens, but there may be a problem of welding.

  I recommend you contact the service again as soon as possible.

  Hello

  Have you noticed yellow exclamation marks in Device Manager next to USB host controllers?
  Check it!

  Even if the yellow exclamation points are not visible in the Device Manager I recommend to remove the USB host controllers and root device manager USB hubs and restart the laptop again.
  Wait that all USB controllers will be recognized by Windows and retest your external USB devices.

  Good bye

• Connection of an instrument with GPIB-USB connection.

  I am trying to use a GPIB-USB adapter to control a unit of Source of LabView. However, I have problems my instrument drivers to recognize the GPIB address specified for the device. I have attached an image below the address specified by IO Keysight connection Expert. I am currently trying to initialized the EMS with the GPIB driver I have attached below. Because of my knowledge limited in LabView instrument control, how should I approach of collecting the correct address of GPIB and recognize it in my VI?

  Hi wyattcurtis824,

  Before we dig into the LabVIEW code, I would recommend a Test Panel of max aperture and trying to communicate with. Are you able to send orders via Keysight connection Expert or NI MAX and see the valid data?

  In addition, when you run the vi in LabVIEW, is pilot it returns an error in the error on the box? If so, what the error is?

  This shoule information help us to the root of the problem.

• HP Envy 15 - q47002 i7: laptop overheating, does not recognize any USB. Even in the Bios.

  Hello

  I bought this product last year, so my warranty wore off.

  My laptop is overheating and it is very slow at this point (even videos are not working well). I tried to clean it up but it was without result.  I want the game and computationally intensive applications, but I'm afraid of the motherboard or hard drive failure.

  Now to the point. I can't install the new OS, any OS because this laptop doesn't have a DVD player and it doesn't recognize any usb 2.0 or 3.0.  I tried to change the options in the Bios and I tried to uninstall and install the drivers (they are up to date).

  What should I do? I can't install a new system because of this problem, and I can't use anything more demanding than youtube which is really annoying since this laptop has good specifications.

  I am currently running Windows 8.1 which I got when I made a purchase.

  I hope someone answers!

  Thank you.

  EDIT: In the Device Manager it says device not installed with yellow exclamation point. By Usb or ext hdd. And it will not find the device-specific drivers. As I never need them on another PC or laptop.

I recommend to restore the default BIOS settings. You could restore the BIOS with this document by selecting the reload the default BIOS settings. In this way, it will look at the hardware installed on your laptop.

  With the USB not recognized by Windows.  Here is a link to solve the USB connections.

  I would like to uninstall everything cited first in the list of universal serial bus controllers.

  Please note remove any and all USB devices and remove the memory card in the slot of the card reader. Disconnect all non-essential devices before you uninstall the controller Universal serial bus.

  Restart your computer, and then insert the USB device.

  You can try to use the Windows Update Troubleshooter to fix updates that do not come through Windows.  Please restart the laptop twice to make sure that all updates are completed!

• How to connect several GPIB-usb-hs instruments?

  I want to know how can I connect several instruments and acquire their signals with a GPIB-usb. I m using 2 multimeters, 1 temp. controller and 1 power supply and I have all the drivers I need. I just need to gather all the drivers 1 prog. to control via GPIB. I have 1 gpib-usb-hs, but I need to read that data from those equips. Any help and advice are welcome.

  Thanks in advance.

  No, what you're asking is done all the time. It must just be a little careful about the management of your written and reads as in most cases, you can connect to only one instrument at a time.

• For some reason, none of my 3 USB keys on my laptop recognize any connection. Help, please.

  It is a follow-up question. My external drives appear in the section work stations. I can access them by along w / the files on it. It's a question that when I'm going to try to send items to readers (all 3 ports) do not recognize that there is a link there. Then, when I click right on and down to ' send to ' drives external hard for these ports (3) none of them don't introduce yourself here indicating that there is a drive attached to it. Therefore, I'm unable to send files to / them. Any port I use at this time.
  Is there a place in my computer, where I have a check to see if I have inadvertently disabled?

  It is a supplementary question that I asked yesterday. Involving essentially the same thing. Then I asked how to send files to my external as disc it does not see the the "send to" when right-clicking. I received a reply and it worked. But it is simply to create a shortcut for the command in the file send to.

  Since I have now come to realize that this is a problem w / all my readers and it's true, create shortcuts for each reader, that I finally hang up the USB hubs will work, it's kind of just put a bandage on the main issue. Problem being, why aren't my grateful USB keys when there is something related to them.

  They have worked in the past. And the only way that they recognize that everything is connected to them is now for me to create a shortcut in the folder send to. Once again, the problem is with Ports USB works not as it should.

  Help, please.

  Thank you

• Satellite A500-141 - the CD/DVD drive will not recognize any disk in the status bar

  I watch the DVD yesterday and he played upward halfway through and almost jerky. Ejected and thought no more of him now, the player will not recognize any disc, be it video or sound. I tried a system restore but still the same thing that it is not read disks. Any help appreciated.

  Thanks in advance.

  Hi quietly,

  If your CD/DVD drive doesn't work, how do you have a system restore?

  Is the CD/DVD drive listed in Device Manager correctly or you see a yellow exclamation mark on it?

  Maybe the lens is dirty and must be cleaned with a Microfiber cloth. Open try CD/DVD and try to clean the lens with a clean Microfiber cloth.
