EV2300 is not recongized by Win 7 64bit this morning.

Hi,

I got a EV2300 to communicate with a BQ27541G1.  It was working yesterday with bqES, and Guage Studio (16/3/2016).  But this morning (17/3/2016). after the windows update completed, it won't be recongized anymore.  I try to recover with a restore point at 16/3 it won't work.  I restore my PC to somewhere in 2014, still not working.

I find a Win XP, with bqES, it work find.

Please help me to fix it because Guage Studio is much much much better, and my PC with 7 is much much much better then my PC with XP.  Thanks!

Best regards,

Alfred Wong
