Firmware
In order to use this device, the sigrok-firmware-fx2lafw (>= 0.1.4) firmware is required.
The firmware was originally written by Jochen Hoenicke (see README for details), thanks a lot!
Note: The firmware is not flashed into the device permanently! You only need to make it available in the usual place where libsigrok looks for firmware files, it will be used automatically (and "uploaded" to the Cypress FX2's SRAM every time you attach the device to a USB port).
Note: On Windows, you will have to assign the WinUSB driver via Zadig twice: the first time for the initial USB VID/PID the device has when attaching it via USB (04b4:6022 or 04b5:6022, depending on which vendor driver is currently being used by the device), and a second time after the firmware has been uploaded to the device and the device has "renumerated" with a different VID/PID pair (1d50:608e).
