USB 2.0 Quick Start
===================
The QEMU EHCI Adapter does *not* support companion controllers. That
implies there are two completely separate USB busses: One USB 1.1 bus
driven by the UHCI controller and one USB 2.0 bus driven by the EHCI
controller. Devices must be attached to the correct controller
manually.
The '-usb' switch will make qemu create the UHCI controller as part of
the PIIX3 chipset. The USB 1.1 bus will carry the name "usb.0".
You can use the standard -device switch to add a EHCI controller to
your virtual machine. It is strongly recommended to specify an ID for
the controller so the USB 2.0 bus gets a individual name, for example
'-device usb-ehci,id=ehci". This will give you a USB 2.0 bus named
"ehci.0".
I strongly recomment to also use -device to attach usb devices because
you can specify the bus they should be attached to this way. Here is
a complete example:
qemu -M pc ${otheroptions} \
-drive if=none,id=usbstick,file=/path/to/image \
-usb \
-device usb-ehci,id=ehci \
-device usb-tablet,bus=usb.0 \
-device usb-storage,bus=ehci.0,drive=usbstick
This attaches a usb tablet to the UHCI adapter and a usb mass storage
device to the EHCI adapter.
enjoy,
Gerd
