From f9e9cff613b8239ce9159735aa662c9c85b478bf Mon Sep 17 00:00:00 2001 From: Yauhen Kharuzhy Date: Fri, 12 Sep 2008 09:02:23 -0700 Subject: [PATCH] USB: Fix s3c2410_udc usb speed handling The new composite framework revealed a weakness in the s3c2410_udc driver gadget register function. Instead of checking if speed asked for was USB_LOW_SPEED upon usb_gadget_register() to deny service, it checked only for USB_FULL_SPEED, thus denying service to usb high speed capable gadgets (like g_ether).
