For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):
Solution
* remove usbutils
emerge -Ca sys-apps/usbutils
* as at this point emerging usbutils is still impossible (now conflict with pciutils) remerge it
emerge -a sys-apps/pciutils
* and now emerge usbutils
emerge -a sys-apps/usbutils
For me it was solved by this:
emerge -av usbutils hwids pciutils
Thanks heinz for a comment, this oneliner is definitely easier and shorter.
I think I tried two of them at one time, but no three and that probably confused portage and made it still to fail.
