Note You must be an Administrator to install NI USB software and devices on your computer. The USB-6008/6009/6501 ships with signal labels. Make sure your NI device is connected to your computer's USB port. Open Apple's System Information (See Determining / Updating the Driver Version for instructions). Click on the menu USB under Hardware. If your NI device is being recognized by your OS X system, its name will appear in the USB Device Tree. The naming of the USB ports may vary.

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. Amcap full version rapidshare files. 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 SP3LabView - 7.0DAQmx - 8.0VISA - 4.4.1MAX - 4.5 (detects both GPIB-USB-HS and USB-6501. Status LED on 6501 continuously flashes)New System:OS - Win 7 EnterpriseLabView - 7.0DAQmx - 9.2.2VISA - 5.0.3MAX - 4.7.4 (detects only GPIB-USB-HS. Status LED on 6501 flashes 3 times and then off). 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 toC:Program FilesNational InstrumentsNI-DAQstagingniemor if 32-bitC:Program Files (x86)National InstrumentsNI-DAQstagingniemlet me know what happens.-gaving. 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 Then I reinstalled NI software in following order, while rebooting after each install:1) LabView 7.02) DAQ 8.0.13) 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 maxreport3-23-11.pdf), now after reinstall its unusable (see attached maxreport3-24-11.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. 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 hereInstalling 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.
