All over the place ;)

Current state:

usb device emulation:
  - usb-storage should work fine on high speed.
  - all others do either emulate 1.1 devices (hid for example)
    or are not yet updated (net for example).

usb passthrough (linux):
  - my usb sticks seem to work ok, didn't test that much though,
    also seeing resets now and then, better don't play with sticks
    holding important data ...
  - the lenovo t500 internal usb camera doesn't work.

Known issues:

"lsusb -v" in the guest often hangs when it tries to query the (not 
existing) debug descriptor.  Most likely a flaw in the ehci error 
handling, maybe not raising a error IRQ where it should.

cheers,
  Gerd
