Replying to [comment:18 alexan...@…]:
> The "usb" group has been created by me as a very insecure solution to
the problem "no way to access a scanner as a user" ... The fine-grained
permissions problem no longer exists, so nothing needs this group,
possibly except emulators that need to access arbitrary USB devices in a
generic way. IMHO, a group is useless if it is not used.
If that's the case, there are several groups in LFS that should be
removed. Without doing an exhaustive check, I don't know of anything
using the bin, sys, or daemon groups although they are "traditional".
I do note that the udev default rules and udev-config/55-lfs.rules use the
group uucp that is not created by LFS. I have created a ticket in LFS to
address this. I am also proposing that LFS drop the usb group completely
and let BLFS handle it completely if needed at all.

create the "scanner" group by default (here you may disagree);
That is an LFS issue, not BLFS. It is a part if the LFS ticket I just
created.
> * all the information about this group (including the udev rule from
the libusb page) should be moved to one place (maybe, the "about devices"
page);
So we should just drop the "Configuring Libusb" section of libusb? Is the
comment in "About Devices", "USB Device Issues" still valid or should
that be dropped too?
> * the reader should be informed about the possible use cases for this
group (i.e., a list of applications that may need this group and can't use
fine-grained permissions) and the risks associated with membership in it.
That's fine. Give me some wording to use. It is contradictory to do that
though if you still say we need to remove the usb group completely.
