The ARMFLY AX-Pro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, and with 2 additional analog channels.
It is a clone of the CWAV USBee AX-Pro. There is an "RS232 RS485 RS422 CAN converter" add-on board which also has a BNC connector for analog support.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
Note: Only the logic analyzer functionality is supported so far, analog support is work in progress.
See ARMFLY AX-Pro/Info for some more details (such as lsusb -vvv output) on the device.

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