[ovirt-users] USB Modem in a VM

[VONDRA Alain]

Hi,
I've tried also to inject the device with virsh attach-device, all seems to work but nothing happen in the VM :

[root at unc-srv-hyp2  ~]$ virsh attach-device unc-srv-prnt3 usb-modem.xml
Please enter your authentication name: root
Please enter your password:
Device attached successfully

What did I do wrong, any ideas ?
Regards
