Add an example devpubd hook that detects the generic USB interface portion of a Tigard debug board and changes the permissions of the appropriate /dev/ugenN.* nodes to allow access without superuser permissions, suitable for using e.g. openocd with the device.
This example can be easily modified to support other generic USB devices that have user-space drivers where running as the superuser is not desired.

Add an example devpubd hook that makes stable path names, using symlinks, for USB serial interfaces, regardless of where the interface is connected or the order of enumeration. This requires the USB device to have a "serialnumber" to function. Examples:
- uftdi serial adapter with two ports:
/dev/tty-uftdi-FT64S4YP-1 -> /dev/ttyU0 /dev/tty-uftdi-FT64S4YP-2 -> /dev/ttyU1
- uslsa serial adapter:
/dev/tty-uslsa-01E7ABCC -> /dev/ttyU4
This allows something like the following in /etc/remote:
sun3:dv=/dev/tty-uftdi-FT64S4YP-1:br#9600:pa=none:dc:
That path will always be stable regardless of which /dev/ttyU* node is actually assigned when the serial adapter is plugged in.
