The XZL_Studio AX 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.
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, as is the independent trigger.
See XZL_Studio AX/Info for some more details (such as lsusb -v output) on the device.

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