hey, Benjamin explained what most probably is going on, see above, so:
1. convice yourself that microsoft isn't using out-of-band data by
sniffing the connection.
2. if not, and Benjamin is right, come up with a timer- and hidraw based
solution (I guess) and convince him and Dmitry to take it.
3. if they don't see any chance to support such broken behaviour in the
kernel, which could as well be and also has it's benefits in some way,
you write the thing in userspace (a tslib raw module is only one example
that would make it easy for you).
Even *if* Synaptics would come up with a firmware update:
1. the current firmware is already out there in the wild;
2. it takes time and work to get people to update
so, if I had the device, I'd write a workaround.
