[Qemu-devel] [Bug 1376798] Re: Qemu does not hotplug (usb) devices

[ManDay]

Please note that since I did not specify a Device ID (a.k.a. Host
Address) but only the bus (3), I'd expect all devices on bus 3 to be
(automatically) added to the guest usb, even if they are plugged into
the host after Qemu is started. I take the liberty of changing the
status to "Opinion", if you still deem it invalid, feel free to close.

** Changed in: qemu
       Status: Invalid => Opinion

Title:
  Qemu does not hotplug (usb) devices

Status in QEMU:
  Opinion

Bug description:
  Qemu passes through all devices on Bus 3 with host-usb all right when
  issued so on the command line such as

  ... -device usb-ehci,id=USBCtrl -device host-
  usb,bus=USBCtrl.0,hostaddr=5

  but it does not pass through the devices newly hotplugged to the host
  after Qemu has already started. One has to explicitly issue

  device_add host-usb,bus=USBCtrl.0 ....

  on the monitor, in order for the guest (Win7 in my case) to see those
  devices.
