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 Cypress FX2 based logic analyzer. This one reports on USB as 08a9:0014 which is CWAV USBee AX-Pro, but contrary to the original (or other clones such as HT_USBee-AxPro), it has no Analog input.
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.
