Hi Robert,

But the hub works just fine when I connect it to my Ubuntu Laptop.
Why doesnt the Beagleboard kernel alone not support it?

Thanks

That's an apples to oranges comparison... On your Ubuntu Laptop you
have a real USB 2.0 port, whereas on the Beagle Cx family it's only an
"EHCI" port.. Please read: Beagleboard:Main Page - eLinux.org

ehci-omap ehci-omap.0: Maybe your device is not a high speed device?
ehci-omap ehci-omap.0: USB host (EHCI) controller does not support full speed or low speed device on it’s root port.
ehci-omap ehci-omap.0: Please connect full/low speed device via a high speed hub. hub 1-0:1.0: unable to enumerate USB device on port 2

Next, based on that error ^^ message, your hub looks to be the older
usb 1.1 based variety...

Thanks Robert.

But I just tested with a newer USB 2.0 High Speed Hub only to get the SAME
messages :frowning: :frowning:
