Hi tech-userlevel@, I just realized that on my regular system, I modified the permissions for the ugen(4) device nodes to allow my regular user to access them:
# ls -l /dev/ugen0.00 crw-rw---- 1 root wheel 64, 0 Dec 22 2014 /dev/ugen0.00 With this, I am generally able to use USB devices attaching as ugen(4) without being root. By default the MAKEDEV script makes these nodes 0600, root:wheel. I also see that in the case of GPIO, we have a _gpio group, and that the corresponding device nodes have permissions set to 0664. Would it make sense to create a _usb group, and setting the permissions of /dev/ugen* and maybe also /dev/usb* to mode 0660 root:_usb? With this we should also be able to run services like pcscd (from pkgsrc) without requiring root. Cheers, -- khorben
