Have a look at the suspend callback code, you see that the USB PHY clock is getting gated. You must ungate before issuing the RWUSIG: /* Ungate PHY clock */ __HAL_PCD_UNGATE_PHYCLOCK((&hpcd)); /* Activate Remote wakeup */ HAL_PCD_ActivateRemot...

Looked at some other example code and noticed that they are using this macro to unlock the USB PHY clock prior to hitting the RWUSIG bit. That fixed it. /* Ungate PHY clock */ __HAL_PCD_UNGATE_PHYCLOCK((&hpcd)); /* Activate Remote wakeup */ HA...

So speaking of open source, can anybody just point me to an example project showing remote wake up implemented on an STM32 ? Often USB-Ethernet bridge devices have Wake-On-Network-Activity capability. That would be a good one. Or just a keyboard ...

From the Universal Serial Bus Specification Revision 2.0, Table 7-2. Low-/full-speed Signaling Levels: Resume signalling for full speed is Data K state, aka Differential "0", which is D- high & D+ lowI'm seeing that the pins are in the Data J state ...
