Michal, here's the output you'd asked for.
I forgot to point out in my last post that in order to stop the panics and get output, I changed fsl_ep_queue() to return -EINVAL when called after fsl_ep_disable() with a NULL "struct usb_endpoint_descriptor *desc".
I've attached two WinXP-SP3 USB Deview html exports (re-posting with text attachments as it was blocked form the list). The first is when plugging in the device with no configuration (previously uninstalled by USB Deview). The second is after unplugging and re-plugging the cable. It seems to get further, as can be seen by USB Deview, and also the Network Control Panel shows the connection as enabled but only briefly before remaining disabled.
As for "lsusb", I was not able to get any output. The applet in busybox didn't have the options you used ("lsusb -vv -d 0525:"), so I built the latest usbutils from SourceForge.net (v0.86). Still it only appears to display info from the port configured in host mode. The port configured for g_ether/RNDIS list nothing even with the -d filter removed and successfully working with a WinCE device.
Instead here's the output from /proc/driver/rndis-000 and /proc/driver/fsl_usb2_udc:

Subject: RE: State of g_ether/RNDIS?
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.
Marc

Subject: RE: State of g_ether/RNDIS?
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.

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?
(Or at least connecting the device to Linux host and issue
"lsusb -vv -d 0525:".)
