From 0ada076819529203e11fcd5d3d52a2c9ada21879 Mon Sep 17 00:00:00 2001 From: OGAWA Hirofumi Date: Sat, 4 Feb 2017 10:16:28 +0900 Subject: [PATCH] nfc: Fix RC-S380* needs zero-length packet 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.
