Severity: important
The udev rules for hackrf devices in
/lib/udev/rules.d/60-libhackrf0.rules do not work for logged in users if
the user information originate from LDAP (ie users that can not be a
member of the plugdev group).
I've investigated and got some help on #debian-devel, and the way this
is supposed to work with logind from systemd is that some file system
ACLs should grant access to the device in /dev/bus/usb/* when the device
is logged in. The rules to set this up is in
/lib/udev/rules.d/70-uaccess.rules. And for software defined radios, I
believe this should be triggered by using ENV{ID_SOFTWARE_RADIO}="1".
Please modify /lib/udev/rules.d/60-libhackrf0.rules to include this
environment setting like this:
ATTR{idVendor}=="1d50", ATTR{idProduct}=="604b",
SYMLINK+="hackrf-jawbreaker-%k", MODE="660", GROUP="plugdev",
ENV{ID_SOFTWARE_RADIO}="1"
ATTR{idVendor}=="1d50", ATTR{idProduct}=="6089", SYMLINK+="hackrf-one-%k",
MODE="660", GROUP="plugdev", ENV{ID_SOFTWARE_RADIO}="1"
ATTR{idVendor}=="1fc9", ATTR{idProduct}=="000c", SYMLINK+="nxp-dfu-%k",
MODE="660", GROUP="plugdev", ENV{ID_SOFTWARE_RADIO}="1"
With this modification in place, the ACLs show up in /dev/ and I can
access the device as a normal user.
Here is the output from 'udevadm info /dev/bus/usb/003/026' with this
setting in place:

Without the setting the TAGS line is missing and logind fail to grant
access to the device.
