That driver was merged during v3.17 merge window, how come it was working for you on v3.12 ? Can you try v3.17, when that driver was merged ? > Here is the trace log when it is first detected : > > <6>[ 126.437000] g_ether gadget: high-speed config #2: RNDIS > <7>[ 126.437000] rndis_set_alt:565: g_ether gadget: init rndis > <7>[ 126.437000] rndis_set_alt:593: g_ether gadget: RNDIS RX/TX early activation ... > <7>[ 126.437000] rndis_open:638: g_ether gadget: rndis_open > <7>[ 126.437000] rndis_set_param_medium:981: rndis_set_param_medium: 0 4259840 > <7>[ 126.437000] rndis_set_param_dev:951: rndis_set_param_dev: > <7>[ 126.438000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l24 > <7>[ 126.439000] rndis_msg_parser:810: rndis_msg_parser: RNDIS_MSG_INIT > <7>[ 126.443000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > <7>[ 126.443000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l28 > <7>[ 126.443000] gen_ndis_query_resp:214: gen_ndis_query_resp: RNDIS_OID_GEN_SUPPORTED_LIST > <7>[ 126.447000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > <7>[ 126.447000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l32 > <7>[ 126.447000] gen_ndis_query_resp:308: gen_ndis_query_resp: RNDIS_OID_GEN_VENDOR_DRIVER_VERSION > <7>[ 126.451000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > <7>[ 126.451000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l32 > <7>[ 126.451000] gen_ndis_query_resp:252: gen_ndis_query_resp: RNDIS_OID_GEN_MAXIMUM_FRAME_SIZE > <7>[ 126.455000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > <7>[ 126.455000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l32 > <7>[ 126.455000] gen_ndis_query_resp:252: gen_ndis_query_resp: RNDIS_OID_GEN_MAXIMUM_FRAME_SIZE > <7>[ 126.459000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > <7>[ 126.459000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l32 > <7>[ 126.459000] gen_ndis_query_resp:439: gen_ndis_query_resp: RNDIS_OID_802_3_MAXIMUM_LIST_SIZE > <7>[ 126.463000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > <7>[ 126.463000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l34 > <7>[ 126.463000] gen_ndis_query_resp:421: gen_ndis_query_resp: RNDIS_OID_802_3_CURRENT_ADDRESS > <7>[ 126.467000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > <7>[ 126.467000] rndis_setup:525: g_ether gadget: rndis req21.00 v0000 i0000 l34 > <7>[ 126.467000] gen_ndis_query_resp:411: gen_ndis_query_resp: RNDIS_OID_802_3_PERMANENT_ADDRESS > <7>[ 126.471000] rndis_setup:525: g_ether gadget: rndis reqa1.01 v0000 i0000 l4096 > > And here is the trace log when I unplug/plug the cable: > > <7>[ 275.026000] composite_suspend:2122: g_ether gadget: suspend > <7>[ 275.141000] composite_suspend:2122: g_ether gadget: suspend > ... what happened during these almost 5 seconds ??

Are you, now, using an atmel provided kernel or actual mainline ? Does it work against a Linux host ? -- balbi
