usb in qemu

How do I actually connect my USB flash to qemu? Documentation says I have to supply qemu with -usbdevice host:bus.addr or -usbdevice host:vendor_idroduct_id, but how do I know all these host:bus.addr?

If you have a bootable image on the flash memory, the command is
#qemu -usb /dev/sdX
To find the actual name of "sdX" please do
#fdisk -l
