Description of problem:

Results of lsusb :

Host machine (RHEL WS 6) 
"Bus 002 Device 006: ID 0529:0001 Aladdin Knowledge Systems HASP v0.06"

Virtual machine on which the usb-passthrough was set :
"Bus 001 Device 001: ID 0000:0000"

The result is the same with a centos 5.5 or a red hat 5 in the virtual machine.

I tried too with a usb key (different ID), with no more success.

Version-Release number of selected component (if applicable):

Up to date version of RHEL WS 6 on 21 feb 2011

How reproducible:

Every time I try to passtrough a usb device to a virtual machine.

Steps to Reproduce:
1. Create / migrate a virtual machine with virt-manager or manually
2. Try to add a usb device with virt-manager or in the vm config file
3. Launch the vm and cry -_- .
  
Actual results:


Expected results:

Physical usb dongle/usb key should be seen by the virtual machines when passed through.

Additional info:

I tried to disable SElinux (SELINUX=disabled in /etc/sysconfig/selinux followed by a reboot). No more results.

The deamon aksusbd was dealing on the host with the usb dongle. I stopped it
No more results.

I tried and installed in /usr/local http://wiki.qemu.org/download/qemu-0.13.0.tar.gz, the keys/usb dongle are seen by virtual machines, so I think there's no problem on the kernel side.
