Thank you for answer.
I understand that the USB suspend is stopping any activity on the bus including SOF for 3ms.
When CYW43907 itself goes to sleep mode, SOF will be stopped. But the another case, if I want CYW43907
to be active and let only USB device goes to suspend, how can I stop SOF ?
Another question is remote resume.
Does CYW43907 support remote resume when it is in sleep mode ?
Thank you for the answer.
I understood that CYW43907 doesn't support Remote Resume.
I focus on resume from USB host to wake up USB device.
Could you tell me how I can stop SOF to let USB device go to suspend ?
And how can I resume USB device from host ?
