Babble is an error condition where a USB device (the ITSEC token)
continues talking longer than it is allowed to. The hub it is
connected to is responsible for detecting this and preventing it from
propagating up to the host. Hubs are complex USB devices, I've had
bad luck with some hubs not working properly. If you have a hub
between the host (PC) and the device (token) when you see the error
perhaps you could try connecting the device directly to the host?

Also, which HC(s) did you see this with? EHCI and UHCI both have the
mapping of babble->EOVERFLOW, but on OHCI EOVERFLOW is used only for
some quirk error during HC startup.. Did you get any other errors
on the OHCI controller that could provide more clues?
