Then it is available in the started VM. But when I switch the usb printer attached to the host off, it disappears in lsusb both on the host and the VM (as expected) but when I switch the USB printer on again, it is shown on the host and also on the QEMU Monitor (Crtl Alt Shift 2 -> info usbhost), but in the VM lsusb does not show it again- so USB pass-through / hot plugging does not work. It worked with a previous Version of qemu (1.0 or something). That is very annoying, because every time I want to print something, I need to shutdown the VM, start the printer, and then start the VM (which runs cups as printer server). But after printing, I do not want the printer to keep running, so I switch it off. To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1377095/+subscriptions
