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