Unable to load the driver USB BT adapter for Aardvark I2C total phase

I tried to install the Total Phase Aardvark I2C USB driver for LabVIEW on two computers and two versions of LV (8.5 and 7.1) without success. The Windows driver seems to work very well as their command center that GUI terminal-esque program works without a hitch, but the DLL LV do not seem to work.

The very simple vi to find the Aardvark USB devices (aa_find_devices) is attached. It always returns the same error code, 8002, which resolves to:

AA_UNABLE_TO_LOAD_DRIVER

-2

Failed to load the USB driver

Their documentation: http://www.totalphase.com/docs/aardvark_datasheet/sect005/#s5.9

It sounds like maybe the DL of LabVIEW, 'aardvark.dll', maybe have a problem of version control. So my question is this: using LabVIEW, how debug DLLs dependencies and solve the problems of this kind? I need the source code for the lib?

See you soon,.

Joe Gorse

This is the "aardvark.dll".

I took a quick peak in the dll provided with the LabVIEW and that comes with the control center with IDA, has seen the same entry points, but that the files were different. So I thought that because the control center worked and did not have the LabVIEW, perhaps the control center dll would work for LabVIEW. After the swap, it worked like a charm.

Thanks for the suggestions!

    I am currently using Windows XP Professional Version 2002 SP3 with specification of my computer as below:

    3.5 GB RAM

    I tried to upgrade to Windows 7 by restarting my computer and boot from the CD. Setup goes as usual, initially, he asked for the language installation during installation, and after I clicked OK, the window titled "Load driver" had appeared with his message as below;

    "To install the device driver required to access your hard drive, insert the installation media containing the driver files and then click OK."

    What are the problems really? Because I think I have all the necessary drivers and before that everything works fine. Where can I get the drivers? And how to solve this?

    Help, please. Thank you. :)

    • Disable the general USB peripherals (for example - smart card reader).
    • If you are using a SCSI drive, make sure you have the drivers available for your storage on a thumdrive device and it is connected. During the installation of Windows 10, click on the advanced custom Option and use the command load driver to load the driver for the SCSI drive. If this does not work and the installer still fails, consider switching to an IDE based hard drive.
    • If you have an external equipment, attached to the machine, unplug them (example, game controllers, USB sticks, external hard drive, printers, peripherals not essential).

    If you try to insert two cards at the same time that would be normal given that the card reader is bound to a single channel of USB. It all depends on how your computer has been configured when it was built.

    If you remove the first card and insert another card it is possible that you are not just right-click on the map in file Explorer and ejecting the card before you remove them.

  • On macOS Sierra - Parallels Desktop 12 - error unable to load Parallels driver - error ID 352

    I have updated at 10.12 some weeks ago, with no problems.

    I used 10 Parallels and put Windows 7 access every day. My Mac software was 100% up-to-date.

    After a few weeks, I started Windows and Parallels showed the error "Failed to load the driver" and KB Parallels, I found that I may need to upgrade. As I was planning to upgrade anyway, I upgraded to Parallels 12 and got the same error.

    I contacted Parallels support - they responded with this:

    Failed to load Parallels driver. Problem ID: 352

    Cause

    The problem is in the bundle /System/Library/Extensions/IOPCIFamily.kext from Apple. In the bundle's info.plist is damaged due to some reasons.

    Resolution

    If please contact Apple Support team and send them system.log and corrupt /System/Library/Extensions/IOPCIFamily.kext/Info.plist.

    The person wrote that if Apple can't help, we will try to help "."

    Is anyone able to help please?

    Thank you.

    It is a user to user forum, not a team of Apple Support forum. In any event, it sounds like a problem of Parallels as it is unlikely that multiple versions of the operating system have defective or damaged kernel extensions.

    For what it's worth, I use Parallels 11 without problem on macOS Sierra to access Windows 2000, Windows XP, Windows XP64, Windows 7 and Windows 10 of virtual machines. I think you should go back to parallels Support. I've avoided Parallels 12 because of all the problems users are reporting

    This vi was initially written for the interface of the scan engine and reused on another project that uses the FPGA interface.
