Hi,

I have 2 questions on Nokia Lumia 800:

1. Does Nokia Lumia 800 support CDP (Charging Downstream Port) charging?
2. If I plugged a mobile device (that does not support CDP charging) into a CDP, will it draw 1.5A?

Thank you in anticipation

Rgds,
Andy

I don't know the answer to #1.

For #2, I believe the host should do a hardware handshake as described in 3.2.3 in the USB battery charging spec before charging begins. But anything is possible.
