But above you said that everything stops when the UHCI driver gets initialized. If it is built into the kernel, then it will be initialized long before the EHCI driver module can be loaded. So this cannot be a communications problem between the two drivers. If you still have the problem in later kernels, you should turn in CONFIG_USB_DEBUG in the configuration and post the kernel log.
