The MCU123 USBee AX Pro clone is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.
It is a clone of the CWAV USBee AX-Pro, but it doesn't have analog (only 8-channel digital) sampling capabilities. It's also very similar to the MCU123 Saleae Logic clone minus the different USB vendor/device IDs.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See MCU123 USBee AX Pro clone/Info for more detailed information on the device.

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