X1000: USB2 (EHCI) connector on the Nemo board

[sailorMH]

Do you use the official A-EON X1000 case and if yes, where is the USB2 port with the USB 2.0 (EHCI) connection?

Hi Christian,
I have official X1000 case, and I have connected front USBs to motherboard and I confirm it has too USB2.0 speed, as Hypex reported.
I tested two USB3.0 flash devices, one in rear port and second in front port ( i.e. connected to motherboard headers )

Speed of copy from USB2.0 port to USB2.0 port is 33.8 MiB/s
It means, ever if SB600 has only one real OHCI controller, thanks to good SB600 internal design (root complex between controllers and PHY) all 10 USB
ports ( 8x rear, 2x motherboard/front) are EHCI capable. And transfer speed between two devices in different port pairs is EHCI.

Thanks a lot for your good explanation.
