how to fix it

Details?  What are you working with?  Is it a serial port or something else?

Usually that means some other program has access to that resource already.  Like trying to run LabVIEW to access Com1, but having that serial port open elsewhere like Hyperterminal.

If this isn't it, you are going to have to give us some real information.

I have been trying to communicate to a USB device ( usb game controller). Then read data from USB game controller by using USB RAW -bulk.vi. However, it appear this error

Hi,

Can you post a screenshot of what your front panel for the USB RAW -bulk.vi and so we can see what you're inputting for the VISA Resource Name? Also, how are you adding the game controller into VISA, does this show up in Measurement and Automation Explorer?

Thanks!

Hello I am also getting a problem with visa write and read.the error code is 0xBFFF0072.can you please tell me how to fix it.

[Dennis_Knutson]

You have one answer. Why can't you provide any sort of details?

[James-D]

Hi ankitsharma,

It would be really helpful if you could post a screenshot of the error you are seeing and give us more information on your application in general. What are you trying to communicate with? How is it connected? Does the device show up in Measurement and Automation Explorer?

I'm getting the same error message. To be precise, the full error message is as follows:

Error opening resource:
ASRL3::INSTR

VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently access it.

I have a LabVIEW program (written by someone else) that monitors the value on an electronic balance that is connected to a desktop computer (Windows XP, 32 bit) via a USB adapter. The program uses the balance reading to measure water flow rate through a membrane filter. The balance shows up in the COM3 port under the Instrument I/O Assistant instrument list but does not currently show up in Measurement & Automation Explorer, although it did earlier (when the program was working). I've successfully run the program MANY times in the past two months, but now today I'm getting all sorts of error messages (this is the most recent one). To my knowledge, I'm not doing anything differently than I was before.

I have LabVIEW 10 installed. I've already tried restarting LabVIEW, restarting the computer, restarting the balance, and re-parsing the output from the balance. None of that fixed the problem.

If you need any other info to help me fix the problem, let me know. I'm extremely inexperienced with LabVIEW, so please spell out everything in basic terms.

Thanks!

Hello DMC,

Have tried to reinstall the drivers of the electronic balance?
