I am using a TPS2511 USB charge controller. It works with almost everything, except a Verizon Ellipsis 7. On that tablet you get a window that says it's an incompatible charger, although it charges anyway. This is an inconvenience to our users. If I use a Maxim USB charge controller that's on one of our older designs then the Verizon Ellipsis 7 works fine with no warning dialog windows. But I'd like to use the TPS2511 because it's cheaper. What do I need to do?
