Some devices that libsigrok can talk to, need a firmware to be uploaded.
libsigrok comes with a set of rules to allow non-root users to upload
those firmware blobs.
Depending on how the system is configured, different set of rules are
needed [0] (yes, it's documented on the fx2lafw page, not on the
libsigrok one [1]). Basically:
- 60-libsigrok.rules is always used;
- 61-libsigrok-uaccess.rules is used when systemd-logind is used;
- 61-libsigrok-plugdev.rules is used when systemd-logind is not used.
For systems without udev, it is the responsibility of the user to
implement proper access management if they need non-root to upload
firmware files.
