Comment (by mmlr):
Almost certainly that is an interrupt issue. The EHCI controller doesn't
get interrupts and is therefore unable to function. Keyboard and mouse
work because they are using a UHCI/OHCI controller that happens to receive
interrupts, or are maybe even using legacy emulation if the controllers
failed to init due to interrupt configuration. If you can provide the
"ints" output from KDL that might show what other drivers may steal the
interrupts. See the Kernel Debugging Land paragraph in ReportingBugs on
how to do that.
