There is not. I haven't had time to maintain the 2.4 version of this driver. If you would like to make the necessary changes and post them as a patch, I'll be glad to check it and submit it for inclusion in the next 2.4 release. > 2.

If you port the usb_gadget_config_ changes, this will no longer be a problem, right?
