Heya Max,
I've never had to install the CH manager on any of my win 7 64bit pc's to make /calibrate any of
my ch hotas setups like you are using....
I also remember the glitch akak is talking about I ver. 4.51 ( or one o f the 4.xx versions )
As for using a powered USB hub... Some people need them while others do not....
I have never had to resort to needing or using a USB powered hub....
and have not needed to use the ch manager on any of the last 7 or 8 pc builds that I loaded with the win 7 ultimate 64 bit os
hope this helps, good luck
TC
