Reply-To: qemu-devel@nongnu.org List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Hello, Currently Qemu does not save/load state information for all usb devices, but only save/load state information for usb-uhci (r5054). Is it enough ? Doesn't Qemu need to save e.g. speed/addr/state/setup_state for USBDevice's ? As a reference look at the patch at the bottom of [1], specifically at generic_usb_save/generic_usb_load.
