util-linux/lsusb.c: print manufacturer/product strings if available 2023-12-13T14:59:47+00:00 Peter Korsgaard peter@korsgaard.com 2023-12-13T13:19:48+00:00 5e0e54827fb0fa80d2c894eb67e8696921095935 Just listing the vendor/product IDs is not always very helpful, so add logic to print the manufacturer and product strings similar to the "big" usbutils versions. Not all devices provide sensible strings though. The usbutils version works around this by falling back to looking up the vendor/product IDs in the hwdb and using those strings instead, which is not an option here - Instead simply trim() the strings for readability. lsusb | sort Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 0bda:5539 Realtek Semiconductor Corp.
