The HT-USBee AxPro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, and with 1 additional analog channels. It is able to switch between USBee AX-Pro, Salea 8 Logic 8 and Altera Usb blaster mode via a button. When pressing the button the usb id changes.
It is a clone of the CWAV USBee AX-Pro.
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.

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