Thanks for the reply. As you can see from my config file, I have uhci_hcd, ehci_hcd and ohci_hcd compiled in my kernel. The messages I get confirm this. The problem seems to be in hub.c where a choice is apparently made to use a slower speed. In case it helps, my /proc/bus/usb/devices file is attached.
