While I'm not against adding libraries to the mingw64 toolchains -- in
fact, I have a number of them in Ports -- is that really your intention?
Would this library be usable from within Cygwin?

From looking at the upstream sources, this is not parallel-installable
with other versions of hidapi, so this should be just
"mingw64-x86_64-hidapi".

This is wrong; VERSION must at least start with a numerical component.

IMO cross-compiler libraries should go into Devel, but I suppose that's
debatable.

> SUMMARY="USB library"

This should be more specific, particularly if you are intending it to be
used with the mingw64 toolchain.

0.8.0-rc1 is the latest tag ("release") in git, so if you want that:

VERSION=0.8.0-rc1
...
SRC_URI="https://github.com/signal11/hidapi/archive/hidapi-${VERSION}/hidapi-hidapi-${VERSION}.tar.gz
SRC_DIR="hidapi-hidapi-${VERSION}"

However, there have been several changes in git since then, so you may
want to include the Windows-relevant ones by adding:

PATCH_URI="
https://github.com/signal11/hidapi/commit/627f3aa478e8099e3660d6a429f1584eeca0724c.patch

https://github.com/signal11/hidapi/commit/54eb31dc16dcc67d0b689ed947bc53a038608c0e.patch
