I was hoping as much. As far as I know, the MG8150 is replacing the  
MP990 which I think is supported.
So would it make sense to check if the code for the 990 works for the 8150?

I already treid something along those lines by copying the line for  
the MP990 instead of the MG6200. Since I didn't know where to find the  
id, I just copied the one from the 990. So since this is the USB id, I  
will connect the device via USB and try what you suggested.

Currently I am using the device via ethernet. Do I still need the USB  
id or should any USB id work? Would it be better to try USB first?

OK. I will try? What is easier to test (or makes more sense) USB or  
ethernet support?

Thanks
