Hi,
Thank you for your answer, I've tried to insert my USB modem, but it doesn't
up in the Windows VM.
I've tried to insert via virt-manager without success, I can't apply the
modification, however I see the modem using lsusb :
lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device
001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID
8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 002: ID
8087:0024 Intel Corp. Integrated Rate Matching Hub Bus 001 Device 003: ID
0624:0248 Avocent Corp. Virtual Hub Bus 001 Device 004: ID 0624:0249 Avocent
Corp. Virtual Keyboard/Mouse Bus 002 Device 010: ID 0572:1321 Conexant
Systems (Rockwell), Inc.
I've unload the "cdc_acm" kernel module via rmmod without success.
I've also tried to edit the xml appending the ID and VENDDOR tags :
<hostdev mode='subsystem' type='usb'>
<source>
<vendor id='0x0572'/>
<product id='0x1321'/>
</source>
</hostdev>
Ut at the first load the config disappears...
Do I need to restart the host or restart libvirtd services ?
Thanks for your help

should be possible using qemu args: -usbdevice host:vendor_id:product_id
in libvirt replace @VENDOR@ and @DEVICE@ to device specific properties:
<domain type='kvm'>
<name>...</name>
…
<devices>
…
<hostdev mode='subsystem' type='usb'>
<source>
<vendor id='0x@VENDOR@'/>
<product id='0x@DEVICE@'/>
</source>
</hostdev>
</devices>
</domain>
if this option is not exposed in ui you can use vdsm-hooks[1] to modify the
libvirt configuration and inject such device.

Alon
