User permission to use USB
I am trying LMDE as a possible replacement for my MATE systems. (That "no more upgrades" caught my eye.) I have been moving along; most things work fine. I did have to download and install humanity packages from an Ubuntu archive. But now I am stopped cold. File /lib/udev/rules.d/50-udev-default.rules has been changed substantially. I used to be able to edit that file and give USB 0666 permission so that I could run a SDR (software defined radio) program as a user. I have copied the lines from the old default.rules file to the LMDE file; I have edited other files in rules.d that seemed to have something to do with USB. Nothing has given me user permission. Thanks for any help you can give me.

Re: User permission to use USB SOLVED
I finally solved the access problem with file /etc/udev/rules.d/50-udev.rules with contents:
# 'libusb' device nodes
SUBSYSTEM=="usb", ATTRS{idVendor}=="16c0", GROUP="dialout"
I don't know why a MODE="0666" simply will not work. Someone must understand the udev rules well enough to explain. I did change the mode of the /dev/bus/usb... file using chmod as root, but that is not something that I want to do every day. I was placed in group dialout when installing LMDE; I suppose other groups might be used as well as dialout.
