with ipso 3.8 i have to use ngai55 for ipso3.8, so download the wrapper and watch the strange errors during upgrade, cross the fingers and keep walking.
the strane thing is that i have a spare lab ip440 and it is working correctly with the old ngai55 (not for ipso3.8), maybe this is the reason for the end of sales of ip440, it is very strong and very simple to replace hardware.
