From a7683eb3af6df30e3a3f3666d834e9abba8f5c22 Mon Sep 17 00:00:00 2001 From: Huang Rui Date: Thu, 22 May 2014 18:06:14 +0800 Subject: usb: usbtest: add pattern check on pipe in phase of unlink read TEST 11 unlinks the URB read request for N times. When host and gadget both initialize pattern 1 (mod 63) data series to do IN transfer, the host side function should check the data buffer if it is as mod 63 series, because the data packet which host receivced will follow pattern 1. So this patch adds this checking action.
