We had many reports of tablets from various brands (Huion, Gaomon,
XP-Pen…) broken in the last release (though working fine when
downgrading to 2.10.6). Latest Huion drivers seem to fix the issue
(according to at least one report), but this is not the case for other
tablets.

Though unable to test myself, provided stderr logs indicate that we hit
the case when 2 devices with the same name are registered. Therefore
this commit is basically reverting commit 717c183a (though keeping and
completing the comments). I don't think there is an ultimate solution
here but with this regression, experience shows us there seem to be a
lot more breakage when overwriting the device with newer occurences (at
least on Windows). It is unclear though if commit 717c183a was also
supposed to fix another case actually encountered. If so, we will need
to get an even more advanced solution.
