Sigh, the power of posting. It works now that I added a permissions rule to /etc/udev/rules.d.
For the record, here is what I did:
(1) sudo vim /etc/udev/rules.d/50-Daisy.rules
(2) added this line:
SUBSYSTEM==“usb”,ATTRS{idVendor}==“0483”,ATTRS{idProduct}==“df11”,MODE=“0660”,GROUP=“MYUSERNAME”,SYMLINK+=“Daisy%n”
with MYUSERNAME being … my user name.
(3) saved and closed that file and restarted my computer.
This assumes you know how to use vim. Use any text editor you like, but you will need sudo for it.
