The Braintechnology USB Interface V2.x is a Cypress FX2 eval board, which can be used as USB-based, 16-channel logic analyzer with up to 24MHz sampling rate.
There are various revisions of the hardware, e.g. V2.5, V2.6, and V2.7.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See Braintechnology USB Interface V2.x/Info for some more details (such as lsusb -vvv output) on the device.
