The default 10 microsecond delay for the controller to come out of halt in dbgp_ehci_startup is too short, so increase it to 1 millisecond. This is based on emperical testing on various USB debug ports on modern machines such as a Lenovo X220i and an Ivybridge development platform that needed to wait ~450-950 microseconds.
