From 984163338a24198863116ccf3e7762fd1fc3c663 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sun, 2 Apr 2006 10:19:23 -0800 Subject: [PATCH] [PATCH] USB: gadgetfs highspeed bugfix This catches up to a change in the Kconfig support for highspeed modes; the change predated 2.6.10, and anyone using gadgetfs on a highspeed device would see the kernel wrongly reject the alternate descriptors.
