To provision for the possible change of size of the ABS namespace, note
that my script already supports a command line option to scan for other
capabilities:
# scan-for-mt-devices --help
Usage: scan-for-mt-devices [OPTIONS]
Options:
-h, --help show this help message and exit
-c CAPABILITY, --capability=CAPABILITY
Capability to look for, defaults to 53
-i FILE, --input=FILE
Input sysfs directory, defaults to /sys/class/input
Hope that comes in handy.
