[PATCH v2 2/2] scripts: imx-usb-loader: print USB VID/PID of excluded devices

[Bastian Krause]

On hosts with multiple USB devices connected, multiple "excluded by
device path option" messages can be observed. Add the USB VID/PID to
these messages to give them some additional value.

Changes since (implicit) v1:
- pass libusb_device_descriptor from find_imx_dev() instead of calling
  libusb_get_device_descriptor() again
