While I agree mostly (ideally) with that argument, it does not really
apply in practice here...
We are using system libusb, because the system libusb is maintained...
To prevent future bugs...
However, we have at this moment a major bug, namely one of the most
common professional spectrophotometers does not work anymore. This is
a significant loss of functionality... Some might call it crippled.
Besides upstream, is there an easy way I can revert the package
sources, to the built-in libusb for my PPA?
