Can someone advice me what can I expect from the USB power consumption of the Mini using imx_4.14.78_1.0.0_ga?

It seems that configuring a USB controller as a gadget (e.g. g_serial) results in a power consumption increase of 315mW. There is no active connection, no traffic, just the gadget configured.


According to AN12410 the power consumption of the processor shouldn't be more than ~240mW even in cases when there is actual data transfer over USB.
