With Fedora and Linux Mint.
I have used udev's rules.d to create links from the product and vendor codes
to names I can create. It would be good to have the links displayed in the
menu. I don't think they're displayed with fldigi but I just enter them in and
it works. The kernel will reassign the USB driver names on a reboot but with
the product and vendor codes installed, a consistent /dev/USB0 for the
TS-440S, /dev/USB1 for the FT-847 CAT, and /dev/USB2 for the TS-440S TX
symlinks will always be accurate.
I hope the symlinks can be displayed in the menu.
