I'm indeed running Debian "bat shit crazy", previously 3.2.0. I've updated to 3.12.9 just now and I don't see any change in downloading from the VT3 though.

3.12.9 was the latest I had easy access to from Debian packages; I can build from source if you think a later version might help though.

No, 3.12.9 is quite reasonable (in a way that 3.2 is not). There haven't been any ftdi changes in this area since, afaik.

Sounds like some other timing difference between Linux and Windows. Maybe Jef can make sense to the logs (and do you have logs with timing from windows for Jef to compare?)

Here's a log from Windows. There appears to be a whole lot less timing precision so it's a bit hard to compare, other than noting the absence of NAKs from the VT3.

I'd try it on Mac OS too but apparently I have to reboot the thing to get the driver loaded and /dev entry created. Happy to try if it would help.
