Unstable USB and SIM connection if upgrade from 7.43

No. I say +WIND message is correctly suppressed by +WFM=0,SIMREMOVE. But hardware state of the pin SIPMRES (pin 10 at SL6087) is never ignored from 7.45. It means SIMPRES pin must be HIGH to keep SIM working independently on SIMREMOVE command.
SIMREMOVE command has no influence on reading this pin from 7.45. As I remember good, this bug was already in some older versions and was described in Release Notes cca 7.42 which I can not find on server now.
SIMREMOVE command should determine if SIMPRES pin is used by SIM holder or not (as described in manual and what was working in 7.43). We make our design without SIMPRES pin and we can not upgrade to 7.45+ because SIM interface is not working if SIMPRES pin is LOW. Am I wrong?
Thanks for comments, best regards…
