For windows you can disable the power management for the controller.
That will cause windows to constantly poll hub status.

For linux you have to reload the uhci hcd driver.  Notice that starting
qemu with -usbdevice works.  The code to implement this is very easy.
You basically set/clear some bits and trigger an interrupt.  See list
archives for example code.
