can't get usb_add to work with kvm 33.

[Andreas Jellinghaus <aj-8LatKXh+/nuGw+nKnLezzg@public.gmane.org>]

I'm using linux 2.6.22.1 with kvm 33, and tried to "usb_add host:1.4"
a device ( a smart card reader ), hoping that it would show up in the
guest and my app could use it via /proc/bus/usb/ like I can do on the
host. my guest is a debian 4.0 ("etch") installation with the debian
standard kernel.

But this doesn't work for me:
(qemu) info usbhost
  Device 3.2, speed 1.5 Mb/s
    Class 00: USB device 0d3d:0001, USBPS2
  Device 1.3, speed 480 Mb/s
    Hub: USB device 04b4:6560
  Device 1.5, speed 1.5 Mb/s
    Vendor Specific: USB device 0973:0001, SchlumbergerSema Cryptoflex
e-gate
(qemu) usb_add host:1.5
(qemu) info usb
  Device 0.0, Speed 1.5 Mb/s, Product SchlumbergerSema Cryptoflex e-g

but no device shows up on the guest.

is this kind of usb bridge supported in kvm?
does it work for you? with kvm version are you using?
using a special guest kernel?
should a normal kernel with no special compile options or patches work as
well?

thanks for your help.

Regards, Andreas
