Re: STM32F103 USB KO after being suspended

Hello,

Thanks for the link. The problem appears with and without hub.
Seems function usb_midi_DataRxCb in usb_midi_device.c is not called after a wakeup. But If I send a second midi data, it works.
Dont' really understand why for the moment... I go on.

regards,

Aurélien

Hello,
I'm using a stlink to program the board. There is no problem at boot, but only when a suspended mode is detected. I don't use any custom bootloader.
