Subject: [PATCH 1/1]linux-usb: fix the product IDs to be little endian in initializers.c
Date: Wed, 6 Feb 2013 17:24:12 +0800	[thread overview]
Message-ID: <fe6feaa260b9.60b9fe6feaa2@huawei.com> (raw)

From: fangxiaozhi <huananhu@huawei.com>

1. The idProduct is little endian, so make the product ID's value to be little endian. Make no break on big endian processors.
