Subject: Windows: Switch to ALLOW_PARTIAL_READS pipe policy enabled by default
X-Git-Tag: upstream/1.0.21~589
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=01da267d93b01b39f7c8102ab32b5b9cae901b4a;p=platform%2Fupstream%2Flibusb.git

Windows: Switch to ALLOW_PARTIAL_READS pipe policy enabled by default

* This avoids an issue when libusbK is used for bulk transfers, which
  is most likely due to a libusbK bug
* See https://sourceforge.net/mailarchive/message.php?msg_id=29736015
