The DreamSourceLab DSLogic Plus is a 16-channel USB-based logic analyzer, with sampling rates up to 400MHz (when using only 4 channels). This differs slightly from the original DSLogic product in its configurable threshold voltage and different PCB layout. DreamSourceLab doesn't make the distinction between these two products very clear on their website.

See DreamSourceLab DSLogic Plus/Info for more details (such as lsusb -v output) about the device.
