Hi,
But the event driven-ness is from the device driver for the host controller pov, and usb redirection is dealing with usb at the device level / emulating a usb device. Has much changed (other then speed) for the way usb looks from the device pov ?
One new thing in usb3 are streams for bulk xfers (Documentation/usb/bulk-streams.txt in the linux kernel source tree has a summary). Also superspeed iso packets can be less than maximum size (IIRC this isn't the case for usb2).
State transitions are a bit different. Also the address assignment: The xHCI handles the address assignment itself whereas with uhci/ehci the guest os handles this.
cheers, Gerd _______________________________________________ Spice-devel mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/spice-devel
