Hi,
I'm using a system based on a cDAQ 9178 (with 2 NI 9223 + 1 NI 9401) with a sampling frequency at 1MHz (the maximum rate).
Using USB3 ports, my application was not able to read the samples on time : buffer overwrite error
Using USB2 ports, everything was fine...
DAQmx version : 9.9 (delivered with the devices)
LV 2011 (run-time)
I don't find any information on NI website. Did anyone also notice this point ?
I didn't check the USB 3 performances, but just used the USB2 instead.
Best regards,
Adeline.
