This way these devices can be put in duplex audio mode. Since this only works if the settings of the endpoint don't change a check is included for this. > > This fixes bug 207023 ("MOTU M2 regression on duplex audio") and should also fix bug 103751 ("M-Audio Fast Track Ultra usb audio device will not operate full-duplex") > > Signed-off-by: Erwin Burema Applied now to for-next branch.
