From 9a37a50349c8d6a7adcee21cefae407fb2f8c623 Mon Sep 17 00:00:00 2001 From: Huang Rui Date: Tue, 24 Sep 2013 00:03:43 +0800 Subject: [PATCH] usb: usbtest: bmAttributes would better be masked When transfer type is isochronous, the other bits (bits 5..2) of bmAttributes in endpoint descriptor might not be set zero. So it's better to use usb_endpoint_type routine to mask bmAttributes with USB_ENDPOINT_XFERTYPE_MASK to judge the transfter type later.
