We're aware of the DX and clones, but they're not quite as easy to support
as regular FX2 boards. The reason is that these have two FX2s + a USB hub
chip in them. One of the FX2s is connected to the analog inputs, the other
to the digital pins. To properly support this device, we need to use the USB
topology calls that are only available in the newest version of libusbx
(1.0.12). So it'll need some libusbx version #ifdef guards.
Then it's just a matter of uploading fx2lafw to the digital-signal FX2,
which should work fine. Currently fx2lafw has no support for analog signals
just yet, but it just needs someone to take it on -- shouldn't be rocket
