[Qemu-devel] [PATCH] [USB] recent fixes

[Lonnie Mendez]

   Hello list.  I've bundled a few fixes recently posted along with a 
modification by myself.  Please find description below and patch attached.

usb-linux.c:

-Modified code in usb_host_scan function to avoid returning information 
on the host's root hubs.  These are the physical ports that the usb 
devices plug in to that show up with product id 0x0000 and vendor id 
0x0000.  This cleans up the information presented by 'info usbhost' by 
only showing usb devices on the system that can be proxied.

hw/usb-uhci.c:

The below changes were submitted by Krister Walfridsson to the list 
recently to allow further functionality with the uhci driver used by 
*BSD guests.

-Changed region number registered with pci_register_io_region from 0 to 4.
-Added USB release value to pci configuration space of the controller.
