See the path code, here....
static int __init udc_init(void)
{
- if (!cpu_is_pxa27x())
+ if (!cpu_is_pxa27x() && !cpu_is_pxa3xx())
return -ENODEV;
printk(KERN_INFO "%s: version %s\n", driver_name, DRIVER_VERSION);

and also u should refer to the code :
170 #ifdef CONFIG_CPU_PXA320
171 #define __cpu_is_pxa320(id) \
172 ({ \
173 unsigned int _id = (id) >> 4 & 0xfff; \
174 _id == 0x603 || _id == 0x682; \
175 })
176 #else
177 #define __cpu_is_pxa320(id) (0)
178 #endif
So i just guess u forget change your configuration about CONFIG_CPU_PXA320.
hope this will give u some help.

> - with module: http://www.keith-koep.com/produkte/xscale-arm-embedded/trizeps5-pxa320.html
> --> It has a PXA320 chip.

> - Kernel version is 2.6.28.7, but slightly modified with patches. Amongst other changes, the patch from http://article.gmane.org/gmane.linux.usb.general/16832 was applied. It should make the file /drivers/usb/gadget/pxa27x_udc.c fit for PXA320. On that website, they say, the patch is for another board (Nomad platform), but this has the PXA320 chip too, so it should work, shouldn't it? Do I have to consider other things, to make the driver fit to my board??

> vfat 10432 0 - Live 0xbf012000
> fat 50012 2 msdos,vfat, Live 0xbf000000
>
> - I also know, which function returns the error "No such device" (-ENODEV), but I think, that the mistake will be somewhere else...
>
> Now I hope, that you can give me some help with that. Maybe someone knows, where I should ask this question better?
