To add to my previous post.
I did use lsusb to find host and bus id.
I added to the string as follows. And i had to run sudo as it complained that it didnt have access to usb nodes.

sudo qemu-system-x86_64 -usb -device usb-host,hostbus=1,hostaddr=24 -device piix3-usb-uhci -enable-kvm -soundhw all -smp 4 -m 2048M -boot d -cdrom /dev/cdrom -drive format=raw,file=hd.img

Doing so I can see that it tries to communicate with the device on the device, but it gives me the following error.
"failed to open host usb device 1:24"
and qemu doesnt start.

Previous message:
All I could find was https://www.linux-kvm.org/page/USB .
I added -device piix3-usb-uhci to my start string and usb hub driver did appear in my device manager on windows 7 pro guest.

The document states that I will have to add strings for every device I want to pass through.

So I have to presumably ruin something like
(qemu) drive_add 0 id=my_usb_disk,if=none,file=usbdisk.img
before running qemu.

So where do I get the details for the device attached to the linux host ?
