Please consistently print GetLastError() values as %u (not %08x or %d),
otherwise the test looks good to me.

Edit every test in tests/devinst.c or only testRegisterAndGetDetail?

My comment was about newly added code. If there are other places, then
they should be fixed as well, but in a separate patch.

Is this just for this file or do you generally want %u instead of %d/%08x ?

I'm just asking as for most of the setupapi errors %08x looks much better than 
%u (and is easier traceable in the setupapi.h include file).

For example:

#define ERROR_INVALID_MACHINENAME 
(APPLICATION_ERROR_MASK|ERROR_SEVERITY_ERROR|0x220)

%u : 3758096928
%08x : e0000220

GetLastError() returns an unsigned value, and winerror.h lists error values
in decimal (if anyone really wants to match a trace with a symbolic name).

That's not strictly true.  The cryptoapi errors are defined as
HRESULTs , but are returned via GetLastError.  More relevant to this
patch is that the setupapi errors are defined as bitmasks, and are
also returned via GetLastError.

I picked %08x for a reason in this code--it's far easier to find the
relevant error using it than using %u.

Then the tests should consistently use %08x, not a mixture of various
formats.

Perhaps.  I generally chose a format that matched the "expected"
error.  Error values like ERROR_INVALID_PARAMETER should be %u--I
erroneously use %d, I think--whereas setupapi errors should be %08x.
But since the ok output is in exceptional conditions, it might be hard
to predict which range of values is more likely, so perhaps
consistency is better than trying to be smart about it.  I don't have
a firm opinion about that.
