  Hi all!

  I have a question about using a DMM (PXI-4065) with VStudio 2008 and Measurement Studio 2009.

  Because DMM are not always supported in .net, I downloaded niDMM.cs 3.0 wrapper of the web site of NOR.

  I also downloaded example c# measure DC Voltsto compare with my request.

  Both an example and my application fail trowing the exception [-1074118656] 'the device was not recognized.  The device is not supported with this driver or version. " class constructor is called.

  DMM = new InstrumentDriverInterop.Ivi.nidmm ("PXI3::12:INSTR", true, true);

  I guess it is function of device PXI!

• The mistake that the USB device is not recognized... Help, please...

  I am trying to connect to Simple external storage drive and once I followed all the steps (only 2) Windows XP gave me a message that the USB device is not recognized or it malfunctioned. I disconnected everything and tried again in another USB port and still had the same error. I know that is not the usb port of my computer because I have it plugged into a port that just worked. I have Windowx XP SP2. Any help on this would be appreciated.

• My USB devices are not recognized, but they have a power

  My USB devices are not recognized, the only ones to be recognized are my mouse and keyboard. Each device is powered (motherboard works fine), but Windows 7 isn't their read (although sometimes I'll get a code 43). I have the latest chipset.

  I tried right click and uninstall each device and rebooted the computer. Nothing has fixed this.

  My external hard drive, ipod and other devices that involve the transfer of data seem to ONLY get power and nothing else.

  It is not material because all my devices work on my laptop. Also my motherboard works fine (it's the 2nd RMA) and it has been tested at the factory to make sure of him.

  I would really appreciate help with this

• Device USB not recognized - device connected USB has malfunctioned and Windows does not recognize it

  I have a HP Pavilion dv4 laptop running Windows 7 Home Edition Premium and the USB ports worked well for a HP deskjet printer and an older Casio digital camera. Then one day, the laptop decided not to recognize the Casio digital camera and gave the error message "USB device not recognized" and also indicated that the device connected to the computer has malfunctioned. This prompted me to buy a new digital camera Canon. Well, a new camera has not fixed the problem. Now, anything that is connected to one of the 2 ports USB will not be recognized by my laptop. Help!  I am at a loss to understand this.  I tried using Microsoft suggested below:

  Suggestion 1: the problem with USB devices, uninstall and reinstall all USB controllers. This allows controllers to recover the port USB of his condition does not respond.
  USB controllers represent the USB ports in Device Manager.

  a. Click Start, type Manager of devices in the search box of start and press ENTER.
  b. expand Bus USB controllers.
  Note: you may scroll through the list to find this point.
  c. the first USB controller under Bus USB controllers right click and then click on uninstall to remove it.
  d. Repeat steps above for each controller USB is listed under Bus USB controllers.
  e. restart the computer. After the computer starts, Windows will automatically check for changes on the hardware and reinstall all USB controllers that you uninstalled.
  f. check the USB device to see if it works.

  This has not fixed the problem.  Then the Device Manager, I tried to update the drivers on all the USB controllers and root hubs. While some may have received software updates downloaded, it still has not corrected the problem of unrecognized USB device after the computer is restarted.  I hope that someone knows the solution to this situation and can pass it on to me. Thanks for reading and any help display.

  Read previous messages revealed the solution for USB devices not recognized on my HP Pavilion as well as several other laptop models.  Shut down the computer and remove the battery and wait for about 15 minutes. Reinstall the battery and restart the computer.  USB ports are working to download pictures from my digital camera from Canon and charging a cell phone, etc...   I hope it helps others with this problem!

• Non-existent devices USB not recognized

  We get the message that USB device not recognized on several machines (Dell Optiplex 980) with XP and the same type of machines with Windows 7. The only USB devices that are attached to the machine are the keyboard and the mouse and the two are identified by the system and are working properly. Mention all the answers that I can find for similar questions about errors for non-existent devices. Can anyone help? Thank you

  No card reader. I submitted this to Dell as the system is a Dell Optiplex 980 and they said that the problem may be with the motherboard that needs to be reset. I tried to unplug the PC from the wall, but that has not solved the problem. They sent a technician with a new motherboard. That did not help. When downloading all the drivers I could find, I noticed that the monitor was turning and all by itself. Also noticed that we had a USB2 cable connection of the monitor to the computer to activate the USB port that is built into the monitor. When I pulled the usb2 to the monitor cable, the error has disappeared and when I plugged it in the returned error. I have this will report to Dell, but in the short term, the problem is resolved.

  I have found a more permanent solution. At the command prompt, type Diskpart

  type

  automount

  If the answer says disabled, type

  automount enable

  Once I did, my USB keys have been recognized automatically when it is plugged.

  Why the setting has been disabled? who knows.

  I hope this helps others.

• NET device is not recognized

  Hi all

  IM the owner of a desktop HP Pavilion all-in-One MS210LA

  Recently, I replaced my corrupted hard drive and re - installed an operating system

  The computer came with Windows 7 Home Basic Edition, but I've upgraded to Windows 7 Ultimate edition.

  My problem now is that my computer is unable to catch up on all the wifi signals. in other words, I can't connect to the internet.

  My guess is that it would be that I have to re - download the driver for my net device? After looking around I could not ideantify the device net im supposed to be looking for the pilot.

  Can someone tell me what is the net device on this computer and provide me with a driver?

  Thanks in advance!
