The Sysclk LWLA1016 is a USB-based, 16-channel logic analyzer with up to 100MHz sampling rate, or up to 250MHz with 8 channels.
Note that sigrok supports only the 100 MHz mode with 16 channels. Supporting the 200/250 MHz 8 channel modes is not worth the effort, since the device does not support triggers in these modes. A non-streaming device without triggers is pretty much useless for any real world application.
See Sysclk LWLA1016/Info for more details (such as lsusb -v output) about the device.

Reverse engineering of the vendor's custom protocol is complete. See Sysclk LWLA1016/Protocol for the findings gathered.
Firmware
In order to use this device you'll have to place the correct firmware files into a directory where libsigrok is looking for them. See Firmware#Where_to_put_the_firmware_files for the OS-specific details.
For the LWLA1016 we provide a script, which can extract them from the vendor software.
First you'll need to install the (Windows) vendor software and grab a copy of its installation directory, e.g. C:\Program Files\LWLA1016 (or similar, depends on where you installed).
Then:
$ git clone git://sigrok.org/sigrok-util $ cd sigrok-util/firmware/sysclk-lwla $ ./sigrok-fwextract-sysclk-lwla1016 LWLA1016 [...] $ md5sum *.rbf 9ea144768afdd3092712075c23eadca4 sysclk-lwla1016-100.rbf 339d71ee799d3d3dbdcbcf1a00aa9f33 sysclk-lwla1016-100-ts.rbf 77fe7158ee53dcbed3bf390ee753594f sysclk-lwla1016-200.rbf e5246f3c1b9e3a34b570af9d50e02cbf sysclk-lwla1016-200-ts.rbf d9f587c9f53d0706f25658bc5580e4f7 sysclk-lwla1016-250.rbf 9d8c284bdbcfbad88aab9c2a79eb783d sysclk-lwla1016-250-ts.rbf
Finally, copy all the extracted *.rbf files to the directory where libsigrok will look for them.
