I wasn't aware of this patch, but actually it looks like your solution is not
really that much different from my one. My proposed patch also transfers both
the input and output buffer as a big chunk of data. In my opinion, all other
alternative (for example transferring only the addresses, and then implement
mapping on top of ReadProcessMemory) would require a much bigger overhead. Wine
is also planning to use the driver framework for input devices, so multiple
wineserver calls back and forth would be bad.

Regarding your project, please note that there is actually ongoing effort to
implement Plug&Play support, HID support, and later also USB support. I'm not
sure if your code is too much specialized for one specific USB Oscilloscope,
but probably some parts (for example libusb handling) could also be useful for
Wine. ;)
