The 128axc-based USBee AX-Pro clone is a USB-based logic analyzer with 8-channel and up to 24MHz sample-rate.
It is yet another clone of the CWAV USBee AX-Pro.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See 128axc-based USBee AX-Pro clone/Info for more details (such as lsusb -v output) about the device.

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