No midi input from Korg PA 500

[afan]

Elglish is not my native, so I'm sorry if this thread is offtopic here.

I'm trying to connect Korg pa 500 with computer trough USB, but it seems, that something is gone wrong: there is no any reaction in external sequencer. Also even midi monitor says that no input is coming.
May be i'm doing something wrong...
Meanwhile file tranfering works normal.



System is Windows 7.
Driver is DrvTools_1_15_r18.
Any installation instructions keeped: installed and checked for proper product name.
External sequencers recognising the connection as "game controller 1" wich is available in device manager.
System's (OS) device manager see it it exactly as Korg PA 500 at sound devices category.

Global MIDI setup at synth checked as "08 external seq".
