I got my hands on a WinCE 6.0 based device and the g_ether/RNDIS appears to run correctly with it. Trying to track down what is going on with Win XP SP3, I captured some kernel logs (left some "fsl_ep_enable" output in there in case it's of any help). In both cases, the target board was freshly booted, the usb0 device ifconfig'd and a DHCP server started. With WinCE there are fewer exchanges before "init rndis" and "rndis open" appear. That's followed by "rndis_set_param_dev:", "rndis req21.00 v0000 i0000 l24", "rndis_msg_parser: REMOTE_NDIS_INITIALIZE_MSG" and many others. With WinXP there is a longer exchange before "init rndis" and "rndis open" appear. Then "rndis_set_param_dev:", "rndis req21.00 v0000 i0000 l24" are followed by "g_ether gadget: suspend". It seems like WinXP doesn't like that "rndis req21.00 v0000 i0000 l24" and fails to reply so linux g_ether/RNDIS times out 5 seconds later. Anyone familiar with RNDIS protocol have ideas of what may be happening here? Thanks.

Thanks Michal, it's good to hear g_ether/RNDIS should be working on 2.6.31. Yes I have tried that latest version of the INF file but it didn't make a difference, at this point I think there is one or two other issues. I will gather more info on the Windows side but first I wanted to bring up the first issue which might effect what it going on later during the RNDIS protocol exchange. After plugging in the USB cable we get a panic. I believe it doesn't occur until we attempt to install the driver/INF on the Windows side, but after that it always occurs when unplugging and replugging. I've added debugging and see that rndis_response_available() passes fsl_ep_queue() an ep who's container has a "struct usb_endpoint_descriptor *desc" which is NULL. This desc is set as part of enabling the ep in fsl_ep_enable() and cleared in fsl_ep_disable(). For some reason replugging in the cable causes 3 fsl_ep_disable(), 2 fsl_ep_queue() and then 3 fsl_ep_enable(). The first of the two fsl_ep_queue() is called with the ep containing the NULL desc. >From the trace below does anyone familiar with the RNDIS code have any idea why rndis_response_available() would call fsl_ep_queue() after a fsl_ep_disable()? Marc P.S. I should also point out the port is FS not HS in case that makes a difference.

Should the existing kernel > code work without patches? Yes, g_ether should work without any additional patches. I've updated the Documentation/usb/linux.inf file in June 2010 (see 90eef5b8acb45: USB: gadget: g_ether: updated INF file) and it should work with anything starting with Windows XP SP3. Could you elaborate on the symptoms on Windows? Could you try installing <http://www.nirsoft.net/utils/usb_devices_view.html> and say what it says?
