From 830d1b188c997c4af094d4e20b194205ddbded13 Mon Sep 17 00:00:00 2001 From: Maulik Mankad Date: Fri, 29 May 2009 18:34:40 +0530 Subject: USB: gadget : Fix RNDIS code to pass USB Compliance tests (USBCV) with g_ether This patch fixes a bug in the RNDIS code. Due to this bug gether_connect() fails as the port remains un-initialized. As a result following USB Compliance Tests were failing. (1)EndpointDescriptorTest_DeviceConfigured (2)Interface Descriptor Test. (3)Halt Endpoint Test. (4)SetConfigurationTest The fix aligns rndis code with the CDC ECM for xxx_set_alt(). The above listed USB Compliance test passes with this fix. Tested working fine on SDP with OMAP 3430.
