`uldaq` Python package says `Error: No DAQ devices found`

Neil BLT


I'm on Ubuntu 18.04 and using Python 3.8 with the latest ULDAQ package versions 1.2.1 and uldaq-1.2.3. My first thought after unboxing the DT9813 DAQ device was to try the `a_in.py` script, but I get the following:

$ cd uldaq-1.2.3/examples
$ python3.8 ./a_in.py

 Error: No DAQ devices found

I find this somewhat confusing because `lsusb` reports a Data Translation device that disappears when I unplug the USB cable:

$ lsusb | grep Data
Bus 001 Device 011: ID 0867:1298 Data Translation, Inc. 

Does anyone know what I'm doing wrong here? I don't think there's a background driver that I need to start manually, right?
