From 13613c133bb8dc70ec404b61345496ba75611dbd Mon Sep 17 00:00:00 2001 From: Robert Baldyga Date: Wed, 2 Oct 2013 11:17:29 +0200 Subject: [PATCH] usb: gadget: s3c-hsotg: fix maxpacket size This patch changes ep maxpacket value from 512 to 1024, because it's needed to handle interupt and isochronous endpoints in high-speed mode. This change doesn't affect on driver functioning, because fifo size (3072) is still enough for the maximum transaction payload (3*1024 for high-speed high-bandwidtch endpoints).
