Unfortunately the stack trace doesn't mention khubd. Undoubtedly the trace overran the kernel's log buffer. You could try reconfiguring the kernel to increase the log-buffer size. Still, the log definitely shows that there's something wrong with ehci_endpoint_disable. Perhaps David Brownell will be able to give you more advice about where to look more closely.
