Greetings,

I'm developing a USB host controller driver for hardware that isn't
available yet.  Is there a way to emulate a PCI host controller for
the Linux host controller driver to talk to?  I looked at the USB
emulation section, but it seemed to be about emulating USB devices,
not USB host controllers.

Also, is the USB emulation in qemu using libusb or usbfs when running
under a Linux host OS?  I noticed the FAQ mentions asynchronous USB
transfers are not possible, which lead me to believe that qemu is
using libusb.

Thanks,

Sarah Sharp

Actually both uhci, ohci and ehci are emulated.

Usbfs is used.
