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. _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
