From a0df64eb273821e6fc9d7a3d3f516d60cb2cb6ac Mon Sep 17 00:00:00 2001 From: ma rui Date: Mon, 1 Nov 2010 11:32:18 +0800 Subject: [PATCH] USB: option: fix when the driver is loaded incorrectly for some Huawei devices. commit 58c0d9d70109bd7e82bdb9517007311a48499960 upstream. When huawei datacard with PID 0x14AC is insterted into Linux system, the present kernel will load the "option" driver to all the interfaces. But actually, some interfaces run as other function and do not need "option" driver. In this path, we modify the id_tables, when the PID is 0x14ac ,VID is 0x12d1, Only when the interface's Class is 0xff,Subclass is 0xff, Pro is 0xff, it does need "option" driver.
