Cool, but it doesn't build as a normal user:

/usr/bin/ld: cannot open output file /usr/bin/lstbt: Permission denied

Why aren't you using autotools to properly be able to integrate into
everyone's build systems?

Also, you are shelling out to bash a lot, and as root, in this program,
are you sure that's ok?

And finally, why not add some of the USB4 stuff to usbutils?  Wouldn't
that be a bit more relevant for people who use those tools already?

thanks,
