[Nut-upsdev] Newhidups gets unbound after a while - Workaround

[Patrick Agrain]

Hi all,

Back from holidays, I worked a little around this problem and found a 
workaround for the non-reconnection of the device.

I comment the 3 tests concerning strings (Vendor, Product and Serial) in 
libhid.c: match_function_exact().
Therefore the match routine gets only busy with the ProductID and VendorID 
and the device is reconnected :

I know this is not the way to correct the problem, but with this workaround 
( invisible from user point of view ), I will have more time to get deeper 
into details. And there is also the disconnection problem to solve.

I will wait for the 2.0.4 version to see what could be integrated.

Note : on my test unit, it is now working the last 15 hours without 
interruption... and continue.
