The measured values are: board idle, looping 9 mA LED on + 5 mA TX CW (+3 dBm) +14 mA ------ 28 mA ====== Adding a margin of 12 mA, we get 40 mA. DFU used 30 mA so far, the application 50 mA. - board.h (BOARD_MAX_mA): define maximum USB bus current - descr.c (config_descriptor), usb/dfu.c (config_descriptor): use BOARD_MAX_mA for bMaxPower instead of hard-coding values
