Date: Fri, 27 Sep 2013 12:31:09 +0200 From: Robert Baldyga <r.baldyga@...sung.com> To: balbi@...com Cc: gregkh@...uxfoundation.org, linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org, b.zolnierkie@...sung.com, m.szyprowski@...sung.com, andrzej.p@...sung.com, Robert Baldyga <r.baldyga@...sung.com> Subject: [PATCH] USB: gadget: s3c-hsotg: fix maxpacket size This patch changes ep maxpacket value from 512 to 1024, becouse it's needed to handle interupt and isochronous endpoints in high-speed mode. This change doesn't affect on driver functioning, becouse fifo size (3072) is still enough for the maximum transaction payload (3*1024 for high-speed high-bandwidtch endpoints).
