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

[ManDay]

Public bug reported:

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.
