To Linux-input team. Good morning.I use the interesting Alfred E.Heggestad 's driver for 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.
