:-O hope you havn't got a heart attack...

I thought you told me that you tested it with a FS.... Maybe I 
misunderstood something.
Ok, put my image to the RAW partiton and executed usbboot again. Still 
the same problem like above...
Copied the image into RAM with usb read (hope it is correct) and then 
bootm. That works.
Then I removed the "if (hdr->ih_magic == IH_MAGIC)" in common/cmd_usb.c, 
set cnt to a suitable value and tested usbboot again. This works, too.

Perhaps I find out how to solve that.

Thanks for your help!
