Thanks Squall.
Could you tell me what is the significance of specifying particular USB
function in first order like
static char *usb_functions[] = {
#ifdef CONFIG_USB_ANDROID_RMNET
"rmnet",
#endif
#ifdef CONFIG_USB_ANDROID_RNDIS
"rndis",
#endif
"usb_mass_storage",
"adb",
//#ifdef CONFIG_USB_ANDROID_RMNET
// "rmnet",
//#endif
#ifdef CONFIG_USB_ANDROID_ACM
"acm",
#endif
};
In above code i putting rmnet to first, what is the significance?
Thanks,
Jagan
