What I am wondering about is why I get ehci in my kernel when I do not
ask for it:
server# grep ehci LINT
LINT:device ehci
So there is a config directive available...
server# grep hci AMD64
AMD64:device uhci # UHCI PCI->USB interface
AMD64:device ohci # OHCI PCI->USB interface
So I have not specified it...
server# kldstat -v | grep ehci
135 ehci/usb
Yet it is in my kernel?
Cheers,
Sean
