Using DirectSound to configure a USB device I see 2 Set Configuration
packets go out over the wire. However using KS mode code setting up the
identical device in an identical mode results in only 1 Set Configuration
packet sent.
The KS mode code then fails when it tries to put the render pin into
KSSTTE_PAUSE (which generally starts the isochronous audio transfer) - no
sensible errors are flagged
Anyone got any ideas about this ? I can supply packet content etc if anyone
wants.
Thx.
