Yes.

Output from mount:
gadget on /dev/gadget type gadgetfs (rw,noexec,nosuid,nodev)


Output from ls /dev/gadget/:
insgesamt 0
dr-xr-xr-x  1 reddog root    0 2007-07-23 11:50 .
drwxr-xr-x 16 root   root 4,4K 2007-07-24 09:53 ..
-rw-------  1 reddog root    0 2007-07-23 11:50 dummy_udc

No i haven't such a message.
But when i type usb_add gadget:1, the qemu says in the QEMU monitor:
(qemu) Could not remove USB device '0.5'
Why? Seems to me like he gets some errors and want trys an automatic
usb_remove...

I killed the qemu much fuster this time an i could see this messages,
too:

I haven't a usb0 device! :-(

SIOCSIFADDR: Kein passendes Gerät gefunden
usb0: ERROR while getting interface flags: Kein passendes Gerät gefunden
SIOCSIFNETMASK: Kein passendes Gerät gefunden

Wow ... it's not ... at first i thought this could it be, but then i
looked in the file ../config-host.h wich is included by config.h.
In ../config-host.h is "#define CONFIG_GADGETFS 1". Or do you mean that
i have to specify the directory /dev/gadget? How can i do this?
