or see attached document

General problem:
Wine 1.6.2
Ubuntu 14.04 LTS

ReadFileEx CompletionRoutine does not take the expected
dwNumberOfBytesTransfered in Ubuntu-Wine compared with windows. In windows
dwNumberOfBytesTransfered is less than or equal to nNumberOfBytesToRead
corresponding to the amount of data available to be read from an external
device, but in Ubuntu-Wine nNumberOfBytesTransfered is always equal to
nNumberOfBytesToRead/Write. Changing COMMTIMEOUTS.ReadIntervalTimeout to be
MAXDWORD does return a smaller chunk of data but does not remedy the problem as
it cuts off the packet. 

When attempting to write into an external device that isn't turned on but
connected by USB, WriteFileEx returns success in both windows and Ubuntu-Wine,
but does not create the correct windows error 87, and the CompletionRoutine
does not execute after the second WriteFileEx.
