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, greg k-h
