The package.manifest only contains packages so it's normal that lsusb 
does not appear there since there's no package *named* lsusb.

E.g. there's no lsusb package in Debian, but you can install it on your 
system via the usbutils package.

However, one can check which package provides the libusb binary by running
oe-pkgdata-util find-path '*/libusb'
it should return usbutils I believe.

Cheers,
Quentin
