Think this is the right place to post. My device is behaving differently under AC-DC USB adaptor vs PC USB.
Setup is: MegaADK Ethernet shield Colour TFT Ethernet 433 router via crossover
The console is displayed with both power supplies but the ethernet connection (data stream for console log) is only active when connected to PC USB.
I assumed my 2A PC USB was more meaty than my mains adaptor but have now tried 2A, 2.5A, 4.2A even. So I no longer think it is insufficient current to run all the components.
Please point me in the right direction if you have something to try, I must be missing something. Thanks.
