Hello, I hit bug https://bugs.launchpad.net/qemu/+bug/685096 and found the usb2.txt file in the source which is sadly not installed by the distribution.
What I would like is an -usb2 option which instantiates both uhci/ohci and ehci root hubs. I don't particularly care if the buses appear as companion or separate. I would also want the -usbdevice host option to attach devices by bus compatibility to either uhci or ehci. The compatibility level is already examined in the libusb code so the information should be available. Then bug 685096 should be resolved by simply specifying -usb2 Before I start butchering the options is there perhaps something like this in progress/planned? Thanks Michal
