Subject: [PATCH 5/9] USB: pl2303: increase bulk-in buffer size to 256 byte
Date: Wed, 17 Mar 2010 23:00:41 +0100 [thread overview]
Message-ID: <1268863245-17230-6-git-send-email-jhovold@gmail.com> (raw)
In-Reply-To: <1268863245-17230-1-git-send-email-jhovold@gmail.com>
The pl2303 requires a bulk-in buffer larger than endpoint size to keep
up at high baudrates without loosing data.
