Firmware
In order to use this device with libsigrok the vendor firmare and bitstream files (v0.97) are required.
Installing firmware files via a bash script
The easiest method to install those is to use the sigrok-fwextract-dreamsourcelab-dslogic script. It will download the correct files, rename them to the correct filenames as expected by libsigrok and install them.
Example usage:
$ PREFIX=$HOME/sr ./sigrok-fwextract-dreamsourcelab-dslogic
This will install the files into $HOME/sr/share/sigrok-fimware. Without PREFIX, the files will be installed into /usr/local/share/sigrok-firmware by default.
Installing firmware files manually
If you want to avoid using the script, you can manually download and rename the files as follows:

You have to place the files into the sigrok-firmware sub-directory of where-ever you installed sigrok-cli or PulseView.
Example run
After firmware is correctly installed, you can see if it's worked like this:
sigrok-cli --driver=dreamsourcelab-dslogic -l 5 --scan
You should see the driver detected and uploading the firmware

Capabilities
Use --show to fetch the current available options
sigrok-cli --driver=dreamsourcelab-dslogic --show
This example shows how to use sigrok-cli to capture 1k samples at 500khz on channels 0 and 1, with voltage threshold of 2.5v
sigrok-cli -C 0,1 --driver=dreamsourcelab-dslogic -c "samplerate=500k:voltage_threshold=2.5-2.5" --samples 1k
This example shows continuous capture (requires the device config to include 'continuous=on')
sigrok-cli -c "samplerate=10k:voltage_threshold=2.5-2.5:continuous=on" --driver=dreamsourcelab-dslogic --continuous
