oh, exclusive mode...very nice! last time I tried a 02US a few months ago it was running KS in shared mode on XP.
the windows master volume shouldn't affect the coax output...strange?! yes the latest beta drivers are always available here: http://www.musiland.com.cn/downloads/drivers/beta/
I'll do the procedure to get the latest firmware update, I guess they'll tell me if I run the latest.
