USB-6009 not recognized by Windows

[WillJ]

I'm having some trouble installing my NI DAQ USB-6009 in Windows 7.

I have installed NI-DAQmx 9.0.2, but when I plug in the DAQ, Windows lists it as an "Unknown Device" for which it cannot find the driver. The LED does not turn on when I connect the DAQ to the computer.

I've tried plugging the DAQ into another computer, but the same thing happens.  How can I fix this?

Many thanks,

Will

I believe the LED should come on when power is applied, driver or no driver.  Try a different USB cable?  Do you have any external circuitry connected to the 6009 I/O connector?  Disconnect that if you do and try it.  Otherwise, you may just have a bad DAQ (it's happened).
