[Qemu-devel] add_usb to a vm

[qemu]

Hi all !

First of all, please, excuse me for my english.

I'm running qemu (kvm) on a debian testing host, qemu version is 0.9.1-1.
I've got a vm that's running windows xp. For testing, i would like to use
an usb device (dongle) needed for me vpn connection (Checkpoint).
In qemu console, info usbhost returning this for the key:

Device 2.3, speed 12 Mb/s
    Class 00: USB device 09c3:0014, Activkey_Sim

result of usb_add host:09c3:0014 :
Could not add USB devices 'host:09c3:0014'

and i get this message in the terminal where i lunch qemu:
usb_linux_update_endp_table: Broken pipe

No problem with other hardware like Webcam or fingerprint sensor, every
thing running well in the VM.

Hardware: intel centrino duo vt capable.
Loaded module: kvm-intel

Same problem with same error message under qemu with kqemu.

With more informations can i give for help understanding what's happening ?

Thanks all for your help !
Wilfried.
