Not a bug, Linux increases the Device ID each time a new device gets
hotplugged. If you need to use this option, pair it with already
connected drivers by parsing the output of lsusb for instance.
You can still use combinations of hostbus, vendorid, productid, etc.

Title:
Qemu does not hotplug (usb) devices
Status in QEMU:
Invalid
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.
