In linux source: \drivers\bluetooth\ath3k.c there is a function like:
static int ath3k_probe(struct usb_interface *intf,
const struct usb_device_id *id)
because you error code is 5, which is EIO, I think something went wrong
here:
if (request_firmware(&firmware, "ath3k-1.fw", &udev->dev) < 0) {
BT_ERR("Error loading firmware");
return -EIO;
}
I'm sure, you could do some test, check the log and figure it out.
Good luck.
