Interesting to know. Do you have a link to that discussion?

Btw, if you could allow my previous message and this one to reach the
mailing list, I would be grateful. That way, it will reach the
archive, where it might help someone else facing the same issue.
Thanks :)

I don't really see how this solves the issue :(

Basically, you seem to be saying that two different people, using
different operating systems with different drivers and different
kernels, testing different printers, should try to squeeze their
reports into *one* H-node entry, just because those two printers have
the same USB VendorID:ProductID string.

This doesn't make sense to me: it is a data structure that is the
wrong shape for the data.

I mean: sure, I *could* edit
https://h-node.org/printers/view/en/1398/Samsung-Electronics-Co---Ltd-SL-M2820DW
and add "Samsung Xpress M2825ND" to the "possible other names of the
device" field, but would be problematic in several ways:

- SL-M2820DW and Xpress M2825ND are not the same printer: the former
is wireless; the latter is not. Giving them the same entry in H-node
might mislead people into believing that they are the same model,
which they aren't.

- I don't know in which year the SL-M2820DW was commercialised. It
might not be the same year as the Xpress M2825ND.

- I performed my test using a different GNU/Linux distro than was used
by the user who added the entry for the SL-M2820DW. Where would I
enter my distro? (Yes, I could put it in the "Description" field, but
then I would be decreasing H-node's utility, by degrading it from a
structured data store into an increasingly unstructured data store,)

- I performed my test with a different kernel than was used for the
SL-M2820DW test. Where should I enter this information? (See point
above.)

- I performed my test with a different driver than was used for the
SL-M2820DW test. Where should I enter this information? (See point
above.)

- I want to add the output of hwinfo to the "Description" field of my
H-node entry, but I do not know whether that output would be relevant
to the SL-M2820DW. Probably not, as they are different printers. So,
where should I put that information?

What would make much more sense to me is to have one H-node report
page per test. That way, the data structure would be the right shape
for the data that users are able to add.

Quite possibly other users besides me have tried to add their hardware
to H-node, only to encounter the same bug as I am reporting, and just
gave up without reporting it. So, the number of previous occasions
this has been an issue might well be more than 2 ;)

It doesn't, for the reasons above :(

Thanks for your help :) Hopefully we can find a solution!
