USB Multiple Interfaces
PostPosted: Sat Oct 31, 2009 8:10 am     Reply with quote
Hello I'm working on a multiple interfaces device based on the ex_usb_kbmouse2.c and the ex_usb_hid.c.
The first interface is a generic HID usb with 64 data payload in and out. The second interface is a generic keyboard interface. The device works fine with these two interfaces. I added one more interface, a mouse interface. The enumeration is completed but the interfaces don´t send and receive any data at all.
Is there a maximum number of interfaces allowed?
Thanks for your time

Javier.
