Inline::MakeMaker is up to date (6.17)

I don't do automated CPAN.pm installs and I don't know what that's supposed to tell you. It suggests to me that you already have version 6.17 of Inline::MakeMaker, which is just brilliant, given that the current version is still at 0.44 !!

You could try (from the CPAN shell) install Inline instead of install Inline::MakeMaker and see if that makes a difference. Or you could install Inline using the same manual procedure that you used with Device::USB.

Cheers,
