The list of connected devices (USB, GPIB, etc.)

For GPIB (actually of GPIB devices connected to the GPIB to USB cable), I do:

static short addrList[31];
    static short listList[31];

    for (j=0;j<31;j++) {
        addrList[j] = j;
    }
    addrList[30] = -1;

    SendIFC(0);
    FindLstn(0,addrList,listList,30);

But do not know how I would do other ports like USB.  I can see it in MAX, but it just seems to appear automatically.

Hello

personally, I use VISA. To find all of the available serial ports, I use viFindRsrc (resource_manager_handle, "ASRL [0-9] *:?") * INSTR", & find_handle & return_count, instrument_descriptor); to the GPIB, you would use "GPIB [0-9] *?: * INSTR"as the second argument.

    [Moved the Forum of the SOUL of the After Effects - MOD forum]

    Hmmm.  It's very strange.  For the experience, I tried to disconnect a sound card, while the SOUL is coding.  I get the message dialog box, but the encoding continues without stopping.  Eventually, this may be specific to certain sound cards.  What is your sound card that you have on your computer?

    For a workaround, could you try checking the "do not show again" checkbox in the message dialog box next time you see it?  Then, click no you should not see this message again and I hope that this problem would disappear.

  • USB-6341 not on the list of simulation devices

    I want to create a USB-6341 siumulated, but this model is not in the list of available under devices simulated in MAX X series devices. I don't see in the devices of series X available for the simulation are PCIe devices. I have MAX 4.7, 9.1.5 DAQmx and LabVIEW 2010. I did this on other computers running older versions of the software and saw this device on the list, so there must be a software component that I have installed, but I can't understand what it is. Any suggestions?

    Richard

    Material of the series X USB were not released before DAQmx 9.2; you need at least this version in order to use a simulated.

  • The list of custom device alias

    Hi all

    I'm trying to retrieve the list of aliases of a custom device and generate a file containing the list of aliases and the reference of the chain. I wanted to do before the depoyment of my device custom (for example, during the initialization stage). I have tried different means:

    (1) from the driver of the RT, I get the reference of the target and navigate the tree of thr to get the aliases Section. The problem is, apparently, that you can not get the aliases section. When I call get target Ref, I received the mention of the controller, and then I managed to get the parent (targets)... but I can't get the root node, and then get the alias Section...

    (2) after that that I wanted to use the API to run. I opened a connection to the workspace, call the list of aliases to Vi... But the problem is when I'm in the my custom device initialization stage, it is not started yet, so it returns an error and that you can not deploy

    (3) my last idea was to use the systemDefinitionAPI. But I don't know how to get the path to the custom device system definition file...

    I think that I have run out of idea... If anyone has a suggestion...

    There is a function on the system definition API you can call directly to translate a reference device custom in the definition corresponding system API node type. This type of node, you can navigate to the root and then find all defined aliases.

    The class is called NodeIDUtil. See the example below. Note there is also some other functions to translate the reference point in node types more specific, as a custom device, channels, etc., waveforms. For example, recorded in 2012.

    Thank you

    Routers "dual-band" can use one or two channels to send a signal to your devices.  If you have not a double router broadband, then it is most likely using the 2.4 Ghz frequency band.  I guess that no one has brought any internal changes to your router recently.

    Have you tried going to the Control Panel/Network and Internet/Network Center and sharing, then the "solve problems" link at the bottom of the page?

    In addition, the first post in this section has some good suggestions: Common corrects problems wireless.

  • Only local users appear in the list of connection

    I installed recently to El Capitan on an iMac and have problems with the users network connection settings. The server is running the Mavericks with OS X Server 3

    The first problem is the login screen. If the value to the list only displays the users created locally on the iMac. It doesn't even have the option 'other '.  If I change to display the username and password I can connect to the network no problem accounts, but this is not what I want.

    File Vault is not lit. The parameters are almost all by default. It's one clean and installation other than the connection to the server and allowing the connection of the network user, I made no changes before my first attempt.

    Since then, I created other local and users made changes to the connection options for the test but nothing else.

    The profile on the Server Manager is configured to display the 'other' and a list of users on the network (I changed a couple of times for the test settings, but nothing changes).

    It may be unrelated, but I found that the other changes in the Profile Manager appear to have no effect. For example, I did one of the users of the network, a mobile account, but he is not ready you as mobile on the iMac.

    Can someone give me tips on where to find the next?

    Is there a reason that you use Server3?

  • L50-B-11J satellite does not recognize the HARD drive connected by USB 3.0

    Hello

    I recently bought a new laptop and install a new legal copy of windows pro 8.1.

    The problem that arises is actually a USB 3.0 port.
    Also, I have a drive external hard support standard USB 2.0 and 3.0.

    When I plug-in the hard drive into a USB 2.0 or any USB 3.0 port (two port supports USB 3.0 is disabled in the BIOS) fine, hard drive is recognized and I can access.

    But, when I plug-in the hard disk into a USB 3.0 port (two port supports USB 3.0 is active in the BIOS) Windows does not recognize it and I can't access it.

    The hard disk led flashes, so it has the power, but does not appear in the devices or Device Manager.
    My opinion is that the problem may be with the drivers for USB, but Toshiba is supported for driver for USB 3.0 for Windows 8.1.

    Then can someone suggest me what to do?

    Laptop: Satellite L50-B-11J
    USB ports: 1xUSB 2.0 port, 2xUSB 3.0 port
    Operating system: Windows Pro 8.1
    USB 3.0 driver: Intel (r) USB 3.0 eXtensible Host Control - 0100 (Microsoft)
    External hard drive: support USB 2.0 and USB 3.0 standard

    Intel USB 3.0 driver is part of the 8.1 Windows System... This is not supplied by Toshiba.

    Windows 7 contains no such USB 3.0 driver and so you can download driver Intel USB 3.0 page of the Toshiba driver as well as the Intel download site.

    By the way: try to disable the functionality of sleep & Charge and check how the HARD drive would work.

    When I move the mouse on one of the list in the control panel or try clicking on it just disappears, also another list, even the desktop icons opens more, when I click on them, they vanish - will not open, when I open 'start' I try to search for a document, it will not even open the folder with the arrow.  Please help, I don't know how it happened, it's very annoying!  I tried looking for the answer.  Not sure if I am in the field of the right question, but can't decide what she made of the object.  H.

    Thank you for your reply - I was able to reassign my 'power' on the keyboard button to shut down the computer, (had disabled), [usually used the Hibernate button], because it would not "stop" on the pop up on the arrow of the Start button, kept disappearing.  I just turned on and everything seems to work again, after checking everything. The only changes were the creation of a network, (had been disabled), I bought a netbook for a wireless connection.   Don't know what caused, but thanks for trying to help me.  Very grateful for this help.

  • Connect devices usb 2.0 at T440s

    I just bought a T440s and I have several USB 2.0 devices I want to use with it. Should which adapter I since the T440s has only USB 3.0 ports.

    USB 2.0 and USB 3.0 are the exact same size / shape / size.

    The only change between USB 2.0 and USB 3.0 is the transfer speed (10 X) and the output amperage (900mA as opposed to 500mA)

    Let me in that way. If your cable does not fit into the USB 3.0, it is not a USB 2.0 cable.

  • IPSec on the Client TCP connections via USB

    We have a problem (and I noticed that several other people here are as well) to our users of broadband remote is not not able to connect. We just recently started getting complaints from users at home XP they were getting errors while trying to connect to the hub.

    To begin troubleshooting we moved our hub 3015 outside our firewall temporarily. Users were still unable to connect. After some additional troubleshooting, we were able to successfully reproduce this problem by simply changing the VPN client to users of IPsec over TCP to IPsec over UDP.

    Then, we tried to identify why she passed to some customers, but not all. In the end, the only thing we could find really different was that customers who have a USB port to connect to the network instead of a correct Ethernet port cannot connect via IPSec over TCP. We have tested and verified on several operating systems, including Windows 2000, XP Home and XP PRO. We have also tested and verified with multiple VPN Clients including 3.5.1 and 3.6.3b.

    The end result is that all case users who use a type USB connection cannot connect via IPSec over TCP. All users who connect through a correct Ethernet adapter are able to connect via another method.

    Our problem is that we cannot run UDP connections behind our firewall without conversion on NAT. We send a client preconfigured to our users which forces to use tcp port udp by default 10000 10000 verses. We do this for several reasons, but the most important of them is our firewall will not redirect sessions IPSec UDP, IPSec TCP sessions only.

    Leaving the VPN concentrator outside the firewall and exposed is not an option. So, I find myself with say to all my users USB that is the only way that they can connect to install an Ethernet card, which ultimately is not really much of an option considering expenditure and technical knowledge necessary to pull it off the coast with hundreds of individuals it just will not fly.

    So, this brings me to this forum. Before I open a TAC case I hear experts to try to determine as closely as possible, if this is a problem of Microsoft or Cisco VPN client. I have my suspicions that this is owned by Microsoft, but I can't prove anything yet. Does anyone else have an idea on this? Please, I invite everyone to test this out and let us know what you find. If you would like more details on the methodology please let me know and I would be happy to provide it. I think it is potentially a huge problem only by the number of complaints I've seen in this forum. My supervisor thinks I smoking something when I try to explain this to him. All he can say is "if it was really a problem, more people would certainly also, and you would have heard about it now, it must be in your configuration." GO FIX"(does all this sound familiar?)

    I appreciate all of the comments that everyone is willing to give. I think that if we as a community get together on this we can find a solution.

    Thanks for your time!

    What dose it mean. and what do I do about it.

    Hello

     
     
    Put the computer to boot and see if the problem persists.
    To help resolve the error and other messages, you can start Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.
     

    Note: follow step 7 to reset the computer to start as usual after the boot process.
     
    Note: Also try unplugging your USB devices (including readers, printers, mouse... all added the USB device) one by one until the message no longer appears.

    Hope this information helps.
