The DreamSourceLab DSLogic is a 16-channel USB-based logic analyzer, with sampling rates up to 400MHz (when using only 4 channels). See DreamSourceLab DSLogic/Info for more details (such as lsusb -v output) about the device.

Installing firmware files via a bash scriptThe 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 manuallyIf you want to avoid using the script, you can manually download and rename the files as follows: Downloaded file Rename to MD5 sum DSLogic DSLogic50.bin dreamsourcelab-dslogic-fpga-5v.fw c3735b82e8b2b8310bec9c2c05ea8b47 DSLogic33.bin dreamsourcelab-dslogic-fpga-3v3.fw 1599ee538d3ff99ddc014b0243cbf60d DSLogic.fw dreamsourcelab-dslogic-fx2.fw 80db51aabc377cb215df2f213621355f DScope DSCope.bin dreamsourcelab-dscope-fpga.fw 80a64ccd9ce8ee71a7165a27dbb30ede DSCope.fw dreamsourcelab-dscope-fx2.fw 4a2ab71e1ef726e2e65019f9d42a6e50 DSLogic Pro DSLogicPro.bin dreamsourcelab-dslogic-pro-fpga.fw 1adf30ff49522cf6944e67b19a8736ed DSLogicPro.fw dreamsourcelab-dslogic-pro-fx2.fw 0555bf649719d11e714f159f2fdc5a57 DSLogic Plus DSLogicPlus.bin dreamsourcelab-dslogic-plus-fpga.fw 0ebc84bf40cf1f9c60998794bc3dba1f DSLogicPlus.fw dreamsourcelab-dslogic-plus-fx2.fw 6f1805fcb5040498ae1b522a7defae5d DSLogic Basic DSLogicBasic.bin dreamsourcelab-dslogic-basic-fpga.fw 3d19924ab211967c2496681fce9e17ed DSLogicBasic.fw dreamsourcelab-dslogic-basic-fx2.fw ab6f5788ce7228ab26933a3cda7abc7bYou have to place the files into the sigrok-firmware sub-directory of where-ever you installed sigrok-cli or PulseView.
