I don't know if its a problem with the driver or g_printer. I debuged both and found that g_printer puts the pnp string in the request buffer int the printer_func_setup function. But the driver never transmit it. What I could not find out is why. I don't have experience with the g_printer gadget so I can't tell if the buffer the string is written into is the right one or if thats the right thing to do.
