Hello list, this may be off topic but it is closely related to my Libvirt adventures so maybe you can help me. I want to pass a USB device (a USB Huawei E620 modem) through to a KVM guest. Pass-through in general works fine and the modem is visible in the guest. However, the host still sees it and sometimes tries to access it (such modems seem to also be USB storage devices). This naturally leads to conflicts and I believe this crashed the guest very badly yesterday. So I am looking for a way to make sure the host passes through the USB device (in its entirety) without trying to touch it and claim it as its own. Preferably without disabling the USB storage subsystem completely on the host. Any ideas? Is there a best practice for such things in the Libvirt world? Or any other world? Thanks!
