Cannot read from USB 6008

[bjbdts]

Hi,

I have PCI6034E and USB6008 installed in the computer. I need to read anlog inputs from both DAQ. right now the problem I have is I cannot read from USB6008. When I look at MAX, I can see the USB device, but there is no "device name", while PCI6034E has "Dev1". When I use "DAQ assistant" to read analog input. My only option is Dev1/ai0, Dev1/ai1... there is no option I can read from USB. This is probably a set up problem. Please help me.

Is the green light blinking on the USB-6008?  When you plugged it in did it search for and install drivers? 

[bjbdts]

Yes. The green light is blinking. Just now in MAX, I found the USB6008 is in the category of USB device, but not under "NI-DAQmx devices" category. I tested the USB6008 with a computer without PCI6034E card, and the USB6008 works.

Inside DAQmx>>My System>>Devices and Interfaces>>NI-DAQmx Devices  what device number is the USB6008?

Try using the attached VI to search for the USB6008 on your system.  It is a handy VI to have for creating tasks programmatically.

Older versions of the USB-6008/6009 had different firmware to run under DAQmx and DAQmx Base. The two were not compatible. If the device was run under DAQmx Base (the only option on Mac OS and Linux), then it would not run correctly under DAQmx (or the other way around). I was told that NI was working on new firmware that would be "universal," but I do not know if they ever developed it.

A firmware updater was available (Windows only) which could load either version of the firmware.

The USB device listing made me think of this as a possibility.

The USB6008 is not in "NI-DAQmx devices" directory in MAX.  It's in "USB Devices" directory. There is only "PCI6034E " in "NI-DAQmx devices" directory with device name "Dev1". My problem is I don't know how to add USB6008 to the NI-DAQmx directory. I downloaded  the latest DAQmx software from NI website and is installing it to the computer. Not sure if this will help.

HI, jmcbee:

I used the "Construct Task.vi", and type in "USB-6008", the program said "Device not found". It gave  "Dev1" to "PCI-6034E".

I installed the DAQmx 8.7.1 software to the computer. But no improvement. Is there anything left that I can try?

This is a long shot but has solved the problem in the past.  Try unplugging the USB6008, and then plugging it back into the computer.  Sometimes after I reboot the computer I have a USB 6211 that isnt recognized, I can solve this issue by unplugging and plugging back in.  Best of luck.
