The HT USBee-AxPro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, with 1 additional analog channel.
It is able to switch between USBee AX-Pro, Salea Logic and Altera USB blaster mode via a button. When pressing the button the USB VID/PID changes.
It is a clone of the CWAV USBee AX-Pro.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.

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