From 845e10d165e03bb2086daa35f37baab7fb960fa2 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 29 Aug 2016 09:57:01 -0400 Subject: tests: test_dfu.py: Add example udev rule for host_usb_dev_node If one does not already have a rule to create a custom device node when a given device enumerates it can be useful to have udev create a bus path based node to the entry in /dev/bus/usb that was just enumerated. Given that DFU itself does not require a /dev entry it is a good idea to provide a rule that will generate one.
