ok, that's something that could work in the future. Attaching the passthru device and usb-tablet to xhci hub in in qemu 2.0 results in qemu aborting when Windows probes the xhci bus. Also the driver Windows attaches after another boot is Renesas. > >> 1) know if the device is usb1/2/3 because here you specify by hand to >> what bus it is attached to and it is not going to be automatically >> attached to the correct bus > > Wrong.

Indeed, weeding out addr and multifunction in ich9-ehci-uhci.cfg still results in working setup. With -net none -readconfig /scratch/qemu/ehci.cfg -device usb-host,vendorid=0x0b95,productid=0x772b -device usb-host,vendorid=0x0a12,productid=0x0001 -device usb-tablet I get networking over the USB Ethernet adaptor (which works only on ehci), the qemu tablet gets attached to ehci and the BT dongle to uhci. Thanks Michal
