It fails here:
/* Microsoft ActiveSync based RNDIS devices lack the CDC descriptors,
* so we'll hard-wire the interfaces and not check for descriptors.
*/
if (is_activesync(&intf->cur_altsetting->desc) && !info->u) {
info->control = usb_ifnum_to_if(dev->udev, 0);
info->data = usb_ifnum_to_if(dev->udev, 1);
if (!info->control || !info->data) {
dev_dbg(&intf->dev,
"activesync: master #0/%p slave #1/%p\n",
info->control,
info->data);
goto bad_desc;
}
} else if (!info->header || !info->u || (!rndis && !info->ether)) {
dev_dbg(&intf->dev, "missing cdc %s%s%sdescriptor\n",
info->header ? "" : "header ",
info->u ? "" : "union ",
info->ether ? "" : "ether ");
goto bad_desc;
}
Change this:
static int is_activesync(struct usb_interface_descriptor *desc)
{
return desc->bInterfaceClass == USB_CLASS_MISC
&& desc->bInterfaceSubClass == 1
&& desc->bInterfaceProtocol == 1;
}
to:
return 1;
