if the device is already booted when connected to the laptop it is shown 
as cdc-ether and works fine.
if the device is switched off when connected to the laptop i get a crash 
/ the usb errors i posted in the last mail.

But let me say again that it well may be that the device is at fault, 
i'm only interested in not having it crash the laptop and not on having 
it work properly as cdc-acm.

thanks,
