AFAIK, you're right, qemu can emulate USB, but it's quite slow, not really
completely implemented yet, and I haven't found a way to boot on such an
emulated usb device in the VM. Sounds like it's more usefull when you want
to hot{plus,unplug} USB devices in a running VM.
So it doesn't appear so reliable nor covering our use cases compared to
the kernel module we are talking about, which is in the kernel tree since
a lot of time and as such is more stable.
I believe that adding this module to the Debian kernel might also be
usefull for Debian Live, but I don't want to speak for them.
