We're not using the firmware and weren't using it before either. Is it possible there was some hack in place to prevent connecting to more than 7 sensors and some update has removed that? I couldn't find anything in "btusb" or "bluetooth" module git logs, though. Unfortunately, the kernel I'm having to use on my machine doesn't have the changes in btusb where it loads the Broadcom firmware for my device. However, I just tried my code out on another machine with a newer kernel (3.13 ubuntu 14.04) AND used the firmware and got the same result, so I don't think the firmware would help in this situation. Without the firmware, the only "driver" that's used by the dongle is btusb, right? Or is that some sort of abstraction layer for something else (a driver that doesn't care if it's usb, pci, etc)? -Tim -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
