I can only assume if it works in 8 it will work in 10. But I don't have a 1641. I would also speculate that the US series use the same drivers. I have an 1800 that works with 10 and I am pretty sure the Us 16X08 uses many of the components that the 1800 and 1641 uses, therefore the same drivers, but this is all speculation.
I am pretty sure many on the board speculate as well, but can't answer the question. Hence, the views but no answer.
