The 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.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See 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.
