With only the EHCI you might have problems redirecting USB 1.1 devices. The EHCI+UHCI magic is the right thing to do for USB 2.0 support on x86. What Andreas and I were suggesting was to split the patch in two parts: first adding support for USB 2.0/3.0, and only then adding redirection (perhaps with the possibility to customize how many redirected devices to support).
