issues with korg nanokontrol and GM5x5x5 driver?

[bosone]

hi!
i have a GM5x5x5 midibox midi interface which works well

 

i have just bought a used korg nanokontrol and i'm trying to install it but it does not work.

i see the driver and the nanokontrol is recognized by windows, but i don't see any MIDI I/o port.

 

i though about an issue with the ploytec MIDI driver.

 

i have tried the nanokontrol on another PC without the gm5x5x5 driver installed and it works.

 

is anyone using the nanokontrol with the gm5 interface?????

 

i'm on win7 64 bit the the driver for the OS is officially supported by korg.
