From 4840ae17ba7e21f2932120383a2c9a0f30e66123 Mon Sep 17 00:00:00 2001 From: Bruno Morelli Date: Mon, 30 Jul 2012 15:26:50 +0200 Subject: [PATCH] USB: isp1362-hcd.c: usb message always saved in case of underrun The usb message must be saved also in case the USB endpoint is not a control endpoint (i.e., "endpoint 0"), otherwise in some circumstances we don't have a payload in case of error. The patch has been created by tracing with usbmon the different error messages generated by this driver with respect to the ehci-hcd driver.
