Interrupt the USB plug PC CVI

When I plug in the USB of my application on the PC, I can communicate with the USB using CVI8.5 and nor-visa link.

I use a method of querying to detect the USB plug. After detecting the USB plug, I initialize the USB link.

How can I generate an interrupt when I plug in the USB application, I need not the method of voting.

Hello Paul,

How good are you with the 'concept' USB?

If I understand correctly, then the problem is not located in CVI itself, but more related to access to USB devices in general.

A guide very useful tool that I myself used also (in a personal atmosphere) is the following:

You write your driver from scratch.

Is there a specific reason why you don't want mark?

Also something useful can be the following document.

The following document could also prove to be very useful:

At a certain level, you should check "windows messages" that are produced by windows. The tutorial above should introduce some of these concepts.

    I get no sound through my USB plug in the headset. But I do get sound by analog channel on my set of speakers. Everything takes?

    I would check the Manager devices to see if all your sound drivers are installed and working.  Click Start, right-click computer, and click Properties.  Then click on Device Manager.  If none of the entries have exclamation points or question marks, you need to get a Windows 7 compatible driver for them.

    I hope this helps.  Good luck.

  • Can I power on the phone with the USB plug in a car

    If I keep the phone into the USB port in a 2011 Camry that will be sufficient to run the GPS function on a long trip? The USB cable is much more flexible that the ADF cable is and will be more aloof.

  • Problem with connecting to the usb storage to the EA4500 via ftp from the internet

    I have trouble to configure my EA 4500 as an FTP server.

    I followed all the instructions according to the manual, but cannot access the USB I connected tot the EA4500 of the internet.

    When I try to connect my own network, everything works fine.

    The configuration I have at home is as follows:

    Cable modem ISP--> EA4500--> all computers.

    As said, I use the EA 4500 as an FTP server.

    If I install an FTP server on one of the computers on my home network and transfer the correct port on the EA4500 for this PC everything works fine and I have access to the internet. Unfortunately, it won't work when using the USB plugged into the EA4500...

    Any help would be great!

    TIA!

    When you go to the EA4500 configuration page, have you enabled the FTP server function?

    When I set mine up, I have was go the section when you set up the USB (shares, etc.) and turned on FTP.

    In the security of the router Security tab, I uncheck the 'Block anonymous Internet requests.

    I do know for sure that you have to uncheck this box, but I always turned off this box, just out of habit when setting up a llinksys router.

    In any case, this is what I did and it worked fine.

    The only other thing I can think is... Your modem is perhaps a nat router. And you have the EA4500 operating on a different subnet. And your modem may possibly be block it.

    What is the brand and model of your modem.

  • How can I disable USB Plug-and-Play?

    Whenever I plug a camera into my USB port, Windows 7 treats as it has never been plugged in before.   When I plug my iPhone or iPad to synchronize with iTunes, Windows 7 starts trying to reinstall the drivers for it even though I just unplugged it five minutes ago.  When I plug my mouse, I get the same thing.  I use a laptop for the convenience of being able to unplug everything, put it in a bag and take it with me.  It is ridiculously annoying having to wait five minutes or more to start using my mouse whenever I put in place somewhere else.  Have to restart iTunes every time I plug in my phone, because Windows decided not to recognize the device even when I had just plugged in a minute there is delayed.  It is a stupid feature, and anyone he designed by default to this mode should be fired for being a fool.

  • MacBook retina cannot find the USB hard drive when it is plugged again

    Hello world

    I have a MacBook retina 2015 computers and a hard drive WD elements USB3 that I use as a Time Machine backup when they travel. The drive is plugged into the USB - C through one of the Apple dongles and when I first start the computer, the USB is mounted and that it appears on the desktop. He does everything very well.

    When I want to take the machine away, I eject it, wait for the secure message and then physically disconnect the drive. However, when I go back and reconnect the drive, the Mac did not see it. The reader will be able as the light comes on and I can hear it turn. Just, it is not mount and is completely invisible for MacOS.

    I checked all connections, even used another dongle - no luck. A disconnect does not set, and I tried to reset the NVRAM. So far, the only solution is to reboot the Mac, afterwards the player reappears - at least until I need to unplug it again.

    Anyone got any ideas what is underway and if there is a fix?

    Thank you very much

    Mike.

    Hello, Mike Richards2,.

    Thank you for using communities Support from Apple!

    This is I think understand that you are not able to see an external hard drive when it is ejected, and then reconnect the computer.  I have some suggestions that I hope will help you.

    It is important to try to isolate what is responsible for this.  The first thing to do to help isolate what is causing the problem is to start the computer in what is called Safe Mode and see if the problem persists.

    Start in safe mode:

    1. Choose the Apple menu > shut down.
    2. After your Mac stops, wait 10 seconds, then press the power button.
    3. As soon as you hear the startup tone, hold down the SHIFT key.
      You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.
    4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

    OS X El Capitan: start in safe mode

    Once the computer is running in safe mode, see if you can duplicate the issue.  If the problem does not appear, go ahead and try to reboot normally again.  If the problem has disappeared, it may have been caused by a problem of file or directory of cache fixed by booting in safe mode.

    If the question comes up, you'll want to check the login items.  Follow these instructions to remove the connection:

    OS X El Capitan: If you think you have incompatible connection points

    Remove the connection, restart the computer and see if the problem persists.

    Have a great day!

    The iPad does not support USB keys. There are some wireless flash drives that can be used, but not the classical records. I suggest you transfer files to a computer and their synchronization then back to the iPad via iTunes.

  • WiFi connectivity weird when I plug in the USB Flash drive?

    I found this WiFi connection problem a few days ago, when I plugged a USB Flash drive in "USB port right side' of my MacBook Pro.

    Every time when USB , WiFi won't work - the connection is lost and can not connect to any hotspot even turn the WiFi market.

    I found more weird, ONLY this brand and model key USB could be the abnormal Mac WiFi.

    This problem will not happen to another USB port even I put the Flash drive in the left side, USB port, weird isn't?

    Conclusion, this flash drive cannot be used with USB port on the RIGHT side, another USB port works fine. If WiFi don't work.

    All other USB devices I've owned are working very well on the USB ports on the right or left side.

    Could Apple support or any helps me to understand why this happen?

    PS. I had the Apple's Diagnostics and received a message "no problem found".

    PS #2. Right - same USB port side and next to the HDMI port on MacBook Pro 13 "model 2015" (snack for someone who confuse average left or right)

  • Interrupted the enclosure or usb-6229 during recording and performance data is now not viewable

    Hello

    I've been recording in Labview SignalExpress 2.5 using the usb-6229 BNC recorder. I was recording on 16 channels with a sampling frequency of 1 kHz over a period of at least 7 hours, while you can imagine a lot of data has been collected. Unfortunately, the power of the recorder was interrupted during recording (but not the PC running Signal Express) and although all the tdms files are present, they will not playback. When I drag the log on in the display area of data, I get the following error message:

    ' The selected journal is ready for posting. You must wait until the log has finished recording to view it".

    If I right click on the journal before sliding above, I get a list of options that is "making visible journal." If I select this, nothing happens at all. If I then right click again, the 'Make visible log' option disappeared. Drag the log on after this step still does not work.

    I recorded other newspapers of more than 7 hours that read perfectly well.

    If the log files be constantly updated during recording, so that if there is a failure of Rubio, the data are not lost?

    The most important thing first, but that is something so that I can play these logs back or are they gone for good? The .tdms file size match those of other file formats that play OK and have the same duration 7hr for registration.

    Thanks in advance

  • PC does not recognize the ipod when I plug in the USB cord.

    I have an ipod touch, and it will replace my old ipod.  When I plug the USB cord, nothing is recognized by the computer.  It is also not recognize my old ipod when I plug it now.  I have other devices that use a USB cord, and they work as they should.

    Apple told me to check with Security Essentials to see if they are blocking a pilot... I am quite at a loss.  It's the ipod or it is safety, or is it the computer?

    I tried everything on separate computers, and they don't always work.

    Any help is appreciated!

    It is not MSE-you get a warning if it were.  Try another cable or try on another PC.  It sounds like the cable might be the problem if all of a sudden or iPod works.

Help, please. Thank you

    Hi Mike,.

    Just to follow up with you on that, that very well may be the cause. Especially when it comes to mobile phones, the real cable you use is very important to have all the features when it is plugged into a computer. Where you can try a new USB cable yet, I hope that whoever is completely compatible with this phone.
