Comment(by frankmpunkt):
I need to correct myself: The patch works as expected (i forgot to remove
g_ether). Anyway, I think it is inode.c (gadgetfs), that needs to be
fixed. Gadgetfs probes the chipset with a fake driver with USB_SPEED_LOW.
But all udc drivers (amd5536udc.c atmel_usba_udc.c fsl_usb2_udc.c
goku_udc.c lh7a40x_udc.c m66592-udc.c omap_udc.c pxa27x_udc.c pxa2xx_udc.c
and finally s3c2410_udc.c) throw an error for drivers with wrong speed
configuration. In combination with all those drivers gadgetfs' probing
would fail. Only dummy_hdc seems to support all possible speed-values...
Anyway, once gadgetfs is mounted, it is usable in combination with
s3c2410_udc, since the user space application that uses gadgetfs should
seem to do chipset-dependent configuration (like http://www.linux-
usb.org/gadget/usb.c does). I wrote a gadget for gadgetfs based on this
example application and i am happy to report, that it works just fine with
OM.
