C-Media CM119A GPIO not reachables with Cm109 driver

[Alain Hervo]

Good morning.
I use the interesting  Alfred E.Heggestad 's driver for driving C-Media 
cm109 usb audio component. 
http://linux.derkeiler.com/Mailing-Lists/Kernel/2008-02/msg03332.html
This driver is useful for accessing GPIO  event.

Now C-Media  CM109 component is replaced by CM119A.
CM119A 's documentation don't  provide difference between CM119A and CM109 
components, except the binterval time : 2ms for CM119A , 32ms for CM109. .

But,  when cm109_usb_probe() is processed,  usb_endpoint_is_int_in(endpoint) 
fails with CM119A component.  : component seems not have accessible 
interrupt endpoint.

Please, do you know this problem ?
Thank you.
Best regards.
Alain.
