This is because wget was executed before the setting up of Internet connection. We should change

After=local-fs.target

to

After=local-fs.target network-online.target

(Just like ​DJ's commit to make-ca.)

BTW it should be man:lsusb(8) instead of man lusub(8).

[Xi Ruoyao]

The same change is needed for pciutils (update-pciids.service).

Fixed in r20738.
