Hello,

I sent this to qemu-discuss a week ago and got no responses, so I'm trying here.

Looking at `qemu-kvm -device ?`, there seem to be multiple usb implementations:
ich9-usb-uhci2
ich9-usb-uhci3
ich9-usb-uhci1
piix3-usb-uhci
piix4-usb-uhci
vt82c686b-usb-uhci
ich9-usb-ehci1
usb-ehci
nec-usb-xhci

Are they all fully implemented and stable? If not, what is the state of each?

Thanks,
Tom
