USB6008 problems reading analog single ended channels AI4, AI5 , AI6

In my USB6008 , I find an error while trying reading on analog port AI4, AI5. I've no problem reading from AI0 to AI3 with NIDAQ base Task.

If in the same task i change channels to AI4 or AI5 i got an error:  Possible reason: Value passed to the task/channels In control is invalid.

Channels in Nidaq are single ended from 0V to 10V  finite sampling 50000Hz   500samples.

how can i read from these 2 channels?

I need some information to understand your problem:
- Why do you use driver DAQmx base instead DAQmx?
-are you using LV or NI data logger?
The sampling rate of 50000Hz is too much. The Max sampling rate is 10KHz.

I use DAQmx base because they gave me it with the board. Now I downloaded DAQmix and installed but it doesn't see the board!

What do you mean by LV or NI data logger?

My board is USB6008.

sorry sample rate is 5KHz

You don't see your device in NI-DQAmx DEVICE because you installed it with daqmx BASE. YOu have to switch the driver: in MAX go in TOOLS>>NI-DAQmx CONFIGURATION>>NI-DAQmx USB DRIVER SELECTOR>>SWITCH and choose DAQmx driver.
