Posted on May 17, 2011 at 12:03Hi, there,
Does anybody there know how to force a SE0 state (both ports driven low) in the USB ports? My USB analyser says that, if I leave the USB ports in this state for 2.5us, the ''hub'' would enter in a default state when no device is connected, so that when the device is connected, it goes to a known state. My USB port will have the keyboard and the mouse devices, and I would like to just ''simulate'' the USB cable being unplugged and plugged without actually doing this. Just resetting USB does not work, it seems that the host doesn't reset, and it loses synchronization with the devices.
Thanks,
Helio Fujimoto.
