There is a linting warning which is independent of this patch.
`guix lint usbutils`
usbutils@010: URI http://www.linux-usb.org/ returned suspiciously small
file (369 bytes)
This seems to be because the website uses frames
for all its actual content.
I guess it's best to ignore the warning. Not sure if
the linter could be made intelligent enough to
handle this correctly.
