[Spice-devel] [spice-gtk PATCH 0/9] Windows: identify USB devices by vid:pid instead of bus.address

[Uri Lublin]

rhbz#842816

It seems that sometimes a USB device's bus.address is changing after
installation of WinUSB driver for that device.
So instead use vid:pid which are consistent across driver installation.

The switch to using vid:pid is done in patch 8/9.

Some code reuses variables named "bus" and "address" to hold vid and pid
values. If people think this should be changed to new variables names (ifdefed)
and/or new function instead of spice_usb_device_manager_get_udev_bus_n_address
let me know.

Using two devices with the same vid:pid on the same Windows client is already
not supported, since Windows installs USB drivers for specific devices
based on their vid:pid

Uri Lublin (9):
  win-usb-dev: make VID and PID available via get_property (Windows)
  win-usb-dev: compare vid:pid instead of bus.addr (Windows)
  usb-device-manager: constify spice_usb_device_get_ functions
  usb-device-manager: find_device: use a match function
  usb-device-manager: find_libdev: use a match function
  usb-device-manager: use a function to get vid:pid from a libusb_device
  usb-device-manager: Windows: spice_usb_device_equal_libdev: compare vid:pid
  usb-device-manager: Windows: identify devices by vid:pid instead of bus.address
  usb-device-manager: fix log messages to match vid:pid change
