The Robomotic MiniLogic is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.
It is a clone of the Saleae Logic.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See Robomotic MiniLogic/Info for more details (such as lsusb -vvv output) about the device.

Protocol
Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
