Subject: [PATCH resend 3/4] nfc: Fix RC-S380* needs zero-length packet
Date: Tue, 03 Jan 2017 14:48:17 +0900 [thread overview]
Message-ID: <877f6clmn2.fsf_-_@mail.parknet.co.jp> (raw)
In-Reply-To: <87bmvolmnt.fsf@mail.parknet.co.jp> (OGAWA Hirofumi's message of "Tue, 03 Jan 2017 14:47:50 +0900")
If sent packet size is wMaxPacketSize boundary, this device doesn't
answer. To fix this, we have to send zero-length packet in usb spec.
