Hi, I'm sure of the device, it's clearer with lsusb, you see all the infos about the device :

Hello, One possibility might be the fact that libvirt itself doesn't have managed mode for USB devices and I'm not sure virt-manager has the appropriate routine handled. Could you try running $ virsh nodedev-list to find the correct usb device and then # virsh nodedev-detach the_usb_device or posibly nodedev-dettach if you run older libvirt? After that, try starting VM with hostdev element added to XML. > Regards > > > > > > > Alain VONDRA > Chargé d'exploitation des Systèmes d'Information Direction > Administrative et Financière > +33 1 44 39 77 76 > UNICEF France > 3 rue Duguay Trouin 75006 PARIS > www.unicef.fr > > > > > ________________________________________ > De : Alon Bar-Lev [alo...@redhat.com] > Envoyé : jeudi 15 janvier 2015 21:23 > À : VONDRA Alain; Michal Skrivanek > Cc : users@ovirt.org > Objet : Re: [ovirt-users] USB Modem in a VM > > Michal, any clue? > > ----- Original Message ----- > > From: "VONDRA Alain" <avon...@unicef.fr> > > To: "Alon Bar-Lev" <alo...@redhat.com> > > Cc: users@ovirt.org > > Sent: Thursday, January 15, 2015 5:56:47 PM > > Subject: RE: [ovirt-users] USB Modem in a VM > > > > 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.
