Why USB-6501 does not install on Win7?

[Vancho]

We are in a process of migrating the test system from old XP machine to the new Win7 system. Everything but USB-6501 got installed correctly. After installing LabView / DAQmx and connecting USB-6501 windows was unable to locate drivers for this device (shows exclamation sign on the device icon in Devices and Printers). MAX 4.7.4 does not detect the device either. I have searched for similar scenarios on NI Forum and abroad and tried suggested solutions. Nothing has worked for me. I know the issue is not with USB-6501 hardware since it is functional on old system. MAX 4.7.4 on Win7 system detects a different USB device just fine (GPIB-USB-HS), but not USB-6501.

Hopefully someone can help us identify the problem we have been struggling with for some time. Below are differences between software loads on both systems:

Old System:

OS - XP SP3

LabView - 7.0

DAQmx - 8.0

VISA - 4.4.1

MAX - 4.5 (detects both GPIB-USB-HS and USB-6501. Status LED on 6501 continuously flashes)

New System:

OS - Win 7 Enterprise

LabView - 7.0

DAQmx - 9.2.2

VISA - 5.0.3

MAX - 4.7.4 (detects only GPIB-USB-HS. Status LED on 6501 flashes 3 times and then off)

Vancho,

What kind of computer are you using? Some computers only have a few powered USB ports, which can cause issues if your not on one of them.

Can you try using the USB port that the GPIB device is plugged into?

Kyle M,

The new system is DELL Optiplex 960.

1) USB-GPIB was connected directly to rear ports on PC.

2) USB-6501 initially was connected through 4 port Linksys hub. (this is how it was originally configured on the old system)

3) Tested USB-6501 connected directly to rear USB ports on PC. MAX still does not detect the device.

Do you see any SW version conflicts on the new system? See attached screen captures for both systems.

Thank you!

What do you see in Device Manager?  A yellow exclamation?  If it doesn't show up in Device Manager (Windows) it surely won't show up in MAX.  If you right click and get "Properties", does it say anything like "Device cannot start" or "Reload the driver"?

Try to "Update Driver" on the Properties page.  Take some screen shots of what you see when going through the steps and post them.  Try pointing directly to

C:\Program Files\National Instruments\NI-DAQ\staging\niem

or if 32-bit

C:\Program Files (x86)\National Instruments\NI-DAQ\staging\niem

let me know what happens...

Gaving,

The device was showing up in Device manager, but with yellow exclamation for no drivers found/loaded. Updating drivers on property page does not help.

So yesterday I spent most of the day removing all NI installations per instructions I found in this forum. Then I reinstalled NI software in following order, while rebooting after each install:

    1) LabView 7.0

    2) DAQ 8.0.1

    3) NI-488.2 (v2.30)

    4) Connected USB-6501 first. The device install went well and it is now being detected in MAX! 🙂

    5) Connected GPIB-USB-HS. Scanned for hardware changes, GPIB device shows up in MAX, but with a weird name listing its INF file in it's name. See below captures:

Incorrectly installed GPIB device:

Correctly installed GPIB device:

The strange thing is that this GPIB device was fully functional on my previous install (see attached max_report_3-23-11.pdf), now after reinstall its unusable (see attached max_report_3-24-11.pdf). Scanning for GPIB instruments using MAX returns no results, but if I reconnect GPIB-USB-HS to old PC system all instruments are detected (for instrument scan error message see attached MAX after reinstall.jpg).

This is my new issue which is unrelated to USB-6501, perhaps I should open a new forum thread.

I agree...you should probably start a thread in the gpib forum and see if those more familiar with gpib could offer some support...I'd link to this post so they know the history of the issues you're seeing.

I'm glad your 6501 is now showing up!  I hope we can get this fixed for you soon!!  I'm sorry it's been a "whack-a-mole".

Hi, sorry i was struggling to find out how to post a new question. So have to Re your answer for a similiar problem.

I have labview 2013 and daqmx 9.7.5 both installed in a proper way. But by any way I cant see daqmx ade appear in the software list in Measurement and Automation. So I dont have any icons for daq under labview.

Wondering why it is like this. Should daqmx ADE be installed automatically when daqmx installation? 

What should I checke now? Thanks.

[gaving]

Did you install LabVIEW first? That's important.

[Baoqing]

Not sure if DAQmx is uninstalled before I install labview2013. But I did re-install DAQmx again after installing labview2013.

[gaving]

As long as you see NI DAQmx Device Driver 9.7.5 in there you should be fine. I'm not sure there's another entry for the api.

I wonder where you are looking in LabVIEW for the DAQmx VIs...are you looking under "Measurement I/O"? If NI-DAQmx is still not there, try running the DAQmx installer again and see if it tries to install anything. If you do not have the driver by itself it can be found here http://www.ni.com/download/ni-daqmx-9.7.5/4240/en/ 

Installing the Run-Time (Core) or (Configuration with MAX) will not get you the API in LabVIEW, you need to install the full driver linked above.

Good luck and let me know
