You need -usb to activated USB support as it is not a default option. I
just booted a GRML [1] live system with this command line into minimal
state (no networking):

  qemu-system-x86_64 -cdrom src/img/grml/grml64-full_2013.09.iso -usb

Ignoring all graphical glitches in the console output, the system works
and USB is supported. lsusb shows one "Linux Foundation 1.1 root hub"
after booting up.

Furthermore, I was able to redirect a USB serial cable with the console
command "usb_add host:0x67b:0x2303" to the VM. It shows up in lsusb and
it created the /dev/ttyUSB0 device that seems to be usable.

Yes, QEMU on Mac OS X is quite slow as it does not get any
virtualization support. By the way, the VirtualBox binaries from
upstream work just fine on Mavericks.
