Subject: [PATCH] node_device_udev: Try harder to get human readable
vendor:product
The manufacurer and product from USB device itself are usually not particularly
useful -- they tend to be missing, or ugly (all-uppercase, padded with spaces,
etc.). Prefer what's in the usb id database and fall back to descriptors only
if the device is too new to be in database.
