It does not matter if it is added via commandline or via device_add on the qemu console. Curious: If a second devices is plugged into the host, nothing happens in qemu. But on the host, the device is detected. If the first device is removed, the second device gets detected by qemu. If then the first device is added again, it gets not detected by qemu until the second device is removed and so on. When adding the devices manually, everything is fine. Confirmed with and without the ehci-patch on qemu-kvm 0.14.0. I first sent the report to the kvm list but it seems to be a pure qemu related issue. Best regards, Erik
