Is CONFIG_USB_EHCI_TT_NEWSCHED enabled in your kernel's configuration?
Can you try with or without a hub?
I can't try with a hub, I don't have any.
cat /boot/config-2.6.31-11-rt | grep CONFIG_USB_EHCI_TT_NEWSCHED
CONFIG_USB_EHCI_TT_NEWSCHED=y
cat /boot/config-2.6.32-24-generic | grep CONFIG_USB_EHCI_TT_NEWSCHED
CONFIG_USB_EHCI_TT_NEWSCHED=y
So CONFIG_USB_EHCI_TT_NEWSCHED is enabled.
Best,
