Dear J�rg,

I applied this series of patches on top of a patch from Stephen Warren from 2014-06-23: [PATCH] usb: ci_udc: fix interaction with CONFIG_USB_ETH_CDC.
Now my USB Ethernet driver does not work anymore. I am using tfpd for downloading files over USB Ethernet Gadget from my notebook to an Freescale i.MX28 board.
It is definitely not wise to testseveral independent changes at once, as you will never know which of them (or any interacton between these) caused the problem.
I strongly recommend to apply only one of these patches iitially, then test it, and only if it works, then apply the second patch (series).
This is the error message:
=> run update_rootfs Updating rootfs ... using ci_udc, OUT ep- IN ep- STATUS ep- high speed config #1: 2 mA, Ethernet Gadget, using CDC Ethernet ERROR: The remote end did not respond in time. at drivers/usb/gadget/ether.c:2383/usb_eth_init()
It would have been helpful to show the actual commands here, instead of referring to "update_rootfs" the definition of which is unknown to us. In any case, this looks like a USB gadget driver related issue, which is independent from Heiko's changes. So I think you wpuld have seen the same problem when testing Stephen's patch alone. You should do that, and eventually report the problem against the "usb: ci_udc: fix interaction..." patch.
The mtd, ubi, ubifs update appears to be innocent here.
Best regards,
Wolfgang Denk
