There is a driver for the madifx that can be extended to work with madifaceXT as well, but only if connected via PCIe: https://plus.google.com/u/1/112574395202528300835/posts/aJSMgiJ4uok As I said a year ago, it should also be possible to sniff the USB connection, but this requires a device and a volunteer to do so. You'd then run Windows in a VM and capture the USB packets with wireshark or any other USB sniffer. Jonathan Woithe may have additional information, since he wrote the drivers for FF400 and FF800. If you feel comfortable doing driver work, you could also reach out to RME and ask for the USB version of their Win32/OSX driver. If you're interested, ping me off-list, and I'll put you in contact with the relevant person. I'm also happy to give you a hand if you want to pursue the PCIe route or do it myself if you can provide me with remote access to the device. I guess it's only 1-3hrs of work, the majority is already there: https://plus.google.com/u/1/112574395202528300835/posts/TXwQkzSGJt5 For the USB equivalent, we probably have nothing at the moment, so you'd need to develop the entire driver, maybe with or without reverse engineering.
