iPhone with KVM?

iPhone with KVM?

[Jun Koi]

hi,

i have a guest Windows on KVM, with iTunes installed on that. then i
let my guest to have direct access to my iPhone connecting to my
physical USB port, using "usb_add" command.
but i got a serious problem: "usb_add" doesnt seem to work, as my
guest Windows never sees my iPhone.

so it seems that giving guest Windows the direct access to USB port is
not enough. any idea why this happens? any solution?

thanks,
Jun

The USB emulaiton in qemu/qemu-kvm doesn't support USB 2.0 at the
moment, only USB 1.1.

Wait for USB 2.0 support to arrive or try to do PCI Passthrough of a
USB card/controller. I have yet to come across a USB card/controller
that actually works with PCI passthrough, though :/

You could also give the ehci branch a try:

git://git.kiszka.org/qemu.git ehci

I merge current qemu master earlier today, but it's not tested yet.
