Hi,

Peter E.>Would it be that sockets 1 and 3 are strictly EHCI?  
The EHCI host controller can only serve high-speed devices (480Mb/s). To maintain compatibility with USB 1.0/1.1, EHCI host controllers are required to route the ports (if connection not fixed) to their so-called companion host controller (Intergrated UHCI/OHCI HC). This ability is explizitly required by the EHCI specification. Your EHCI host controller has two OHCI companion host controllers. It would be interesting if you could report the port count of these two companions. AosUsbOhci.Diag should be useful.
 
Peter E.>Is there an Aos replacement for Usb.Info? 
AosUsb.Info shows current USB topology.
AosUsb.ShowDrivers shows current installed USB device drivers
AosUsbOhci.Diag will display some information about the OHCI host controllers, in particular, how many ports they report.
 
Regards, 
Sven Stauber
