I am investigating if it is possible to use the CDC composite gadget driver available in linux 2.6.27 together with an Atmel AT91SAM9260. As I understand it needs a USB host port with at least 6 endpoints. When I read the datasheet for the processor it states that it haves six endpoints in its usb device port, 2 control/bulk/interrupt and 4 bulk/iso/interrupt. When I read about the at91 udc driver USB_GADGET_AT91 in kernel configuration it states "Many Atmel AT91 processors (such as the AT91RM2000) have a full speed USB Device Port with support for five configurable endpoints (plus endpoint zero)." I have tried to load the USB composite driver and it fails with error -19 ENODEV when it tries to allocates endpoints. So I wonder about the endpoint zero, can it be used in a gadget driver? Or is it reserved for another purposes? /Johan -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
