>From 04eab836f639f16ffff09b85774ced6538509fb7 Mon Sep 17 00:00:00 2001 From: Andiry Xu <andiry.xu@xxxxxxx> Date: Fri, 5 Nov 2010 15:18:04 +0800 Subject: [PATCH 2/3] xHCI: fix wMaxPacketSize mask USB2.0 spec 9.6.6 says: For all endpoints, bit 10..0 specify the maximum packet size(in bytes). So the wMaxPacketSize mask should be 0x7ff rather than 0x3ff.
