• USB device not detected.

  Original title: USB device

  I can't get Windows 8 to detect my USB video to DVD connector. I installed the necessary drivers but nothing seems to work.

  Thank you for your answer

  Apparently, the USB connector is damaged or has simply not. I took it to a computer store, their computer could not detect the connector either. I think I'll buy another connector $ 49 after only 3 years.

• USB devices are detected, but I can't access any fles

  Hello

  Ive had a very weird problem.  Everything was fine until this afternoon.  I unplugged a usb (Sandisk blade) flash drive and when I put a new one in I couldn't access the files.  He says drive D was there, but I couldn't access it and everything he told me to do, it was to format the drive.  I tried the same thing with other readers and portable hard drive and it's the same thing. I tried these on other machines, and they work very well which seems to indicate a problem with my system.  I had done a few updates for .net, but I uninstalled them I'm sure. They appear in Device Manager.  Said of the USB storage device usb and HARD drive said it was something another beginning with I (device inditto or something.  It escapes me at the moment.  Something like Indento device or something.  I tried to uninstall only for devices to be taken back, with their correct names, and he says that the facility is very well, but still I can't access it. When I click on them.  A couple of times I tried to let the readers and they seemed fully functional, but once I got out them again the problem starts again.  I tried to reassign the drive, turning letters works, plug in the usb key and auxiliary ports and now I am at my wits end.  If someone out there can help, I would be very grateful.  My specs:

  Original title: open usb drivers problem

  My Dell laptop stops working with USB storage drivers. The removable driver icon is displayed in the devices window and printers with a yellow triangle around!
  I've tried different USB drivers and the problem persists. I tried troubleshooting, and it does not help.
  In the Properties window, I get the following message:

  You are welcome.

  Something seems not quite right so contact the store can be a good idea.

• SetPanelAttribute blocks the detection of USB devices

  I'm developing an application for 2010 LabWindows that reads and writes to a Board of material via a USB connection.  The program Initializes the interface at startup by calling InstallWinMsgCallback to detect WM_DEVICECHANGE messages to the main panel.  The callback receives the WM_DEVICECHANGE message and detects if power has been turned on or off on the Board of directors by seeking wParam == DBT_DEVICEARRIVAL (powered) or DBT_DEVICEREMOVECOMPLETE (off).  Device in lParam information is used to configure the jury.  The recall also receives messages with wParam WM_DEVICECHANGE is DBT_DEVNODES_CHANGED, but does not account for these.

  Our application can be controlled by the user or a server program "automation."  When Automation is enabled, the application disables input on the main panel.

  The problem I see is that when some attributes of the main panel are set to false (including ATTR_MOVABLE and ATTR_CLOSE_ITEM_VISIBLE), the USB interface crashes.  The accident is indicated by a another message is posted on the recall with a message of 1004 (hex 3EC) ID, even if InstallWinMsgCallback has never been called with this message ID.  Once the accident happens, the program no longer detects when the power to the Board of Directors is enabled or disabled.  The reminder will always receive messages DBT_DEVNODES_CHANGED when the Board is powered on or off, but not DBT_DEVICEARRIVAL or DBT_DEVICEREMOVECOMPLETE.

  I looked for more information on the meaning of the error code 1004 on various sites from this list WM_xxx message opcodes, but this code is not listed.  I also noticed that after the crash, the program will always continue to process all messages for other USB devices - for example, if I plug a portable USB drive into the port on the PC.  Only the material Commission detection is affected.

  Does anyone have an idea what could be the cause?

  Rich Ferrara

  Rich,
  After looking at your code, I think that the mistake may be connected to the call of InstallWinMsgCallback(), then manipulating the Panel message related to recall.

  If you manipulate the Panel by changing its attributes, I think you have to call RemoveWinMsgCallback() to remove the handler and then call InstallWinMsgCallback() to reactivate. Please try to modify the code to remove and install the callback when the manipulation of the appearance of the window.

  This may not affect you, but in the documentation of the function InstallWinMsgCallback(), it says "a message callback cannot be installed for a child of LabWindows/CVI group."

  Hello

  I have a workaround for this problem that occasionally occurs. It's just to reconnect the USB hub (as recommended by Windows). I was wondering if anyone knows why this happens and how to fix it. The error is: -.

  "Unrecognized USB device. One of the USB devices attached to this computer has malfunctioned and windows does not recognize.

  Roob (2 ports) USB hubs - unused Port, unknown device.

  I can't wait to hear back on your part.

  Hello Julia

  It is always advantageous to mention which model you have exactly. Of course the external device is not correctly recognized. Check if there is a driver that must be installed before you can use it properly.
