Broadcom Bcm2070 Bluetooth Device Driver For Mac

Google shows that problems with broadcom devices are common and the usual solution is to extract a proprietary firmware file from the windows driver (AskUbuntu, Arch Wiki) but in my case the driver does not specify a firmware file in the *.inf file.

From the Linux Operating System perspective the above gives us two majorlayouts of components in the wireless stack: When the wireless device is a SoftMAC device, thekernel will use a specific Linux Kernel Module (LKM) called 'mac80211'. This driver exposesthe MLME API in order to manage the Management frames, otherwise the kernel will use directly a hardware driverand offload MLME processing to the chip's firmware.

As the firmware code and the wl proprietary driver share a lot of code, we found the same issues in the driver. This means that on systems using FullMAC devices an attacker controlling a malicious Access Point can compromise the chip, whereas on systems with SoftMAC devices an attack would lead to direct compromise of kernel memory.

These issues were present in all the firmwares analyzed, and in all versions of the wl driver analyzed. However, although the code is present on all firmwares, it doesn't seem to be used on all versions. For example, it's not used on the firmware version of the bcm4339 that we analyzed but it's used on all firmware's version of the bcm43430 device.

Please note that the Linux compatibility statements here will almost certainly apply to any Bluetooth adapter connected to a Linux PC, not just the Plugable Bluetooth adapter. This is because if Linux supports the driver for a Bluetooth adapter (the driver for the Plugable Bluetooth adapter is built into modern Linux kernels), the device and Bluetooth profile compatibility is still dependent on BlueZ and Pulseaudio which handle data and audio communicated via Bluetooth.There are currently ongoing issues with the BlueZ project, particularly surrounding audio support. Because of these issues, we currently consider Linux incompatible with the adapter.

On Windows, if a profile is missing, usually the device will still complete the pairing process. Once pairing is completed, Windows will attempt to assign driver functions to the profile identifiers that it detects. Errors like "Driver Not Found" or "Error Installing Driver" are a typical behavior from Windows when profiles are missing.

Without support for BLE, earlier versions of Windows can get confused about how to handle BLE features on devices that have them. This can manifest in a variety of ways such as the PC showing that there are devices it cannot find drivers for, or it may simply appear that a device is connected but won't function. On Windows 7, this can be somewhat addressed by installing the driver version that we have available for download, rather than the one on the CD that comes with the adapter. This should at least correct issues with newer audio devices that have BLE features.

But I strongly doubt, that you'll get past the ./ I still didn't get any of the bcm20702 based adapters, so I actually never ran the script.btw, I have already started writing a driver module. When I'm done, I will need someone capable of building a custom, patched kernel for testing.

You may get the BCM20702a0 driver problem solved by installing the Broadcom driver. Windows drivers for Broadcom Bluetooth devices are no longer available on the official website. They should be included in the Optional Updates subsection of the Windows Update.

You can also choose Uninstall device in the right-click menu. Then, restart the PC to let Microsoft Windows search, download, and install the latest driver for BCM20702a0.

Most of you can get rid of the BCM20702a0 driver Windows 11 error with one of the above solutions. Yet, if unfortunately, your problem persists, you need to contact the Bluetooth device driver manufacturer for help.

After some researching I found this bug report. The bug reported by this link is similar to what happened to my system. This occurs when I do a hot reboot from Windows to Ubuntu and the solution that worked for me is to do a cold reboot whenever I use bluetooth device on Windows.

I had this same problem after updating Kubuntu to 20.04, tried reinstalling several times to no avail.Then I noticed that the bluetooth didn't fail (White LED) until I logged-in, after some testing it turned out that disabling "Enable bluetooth integration" inside bluetooth settings and reloading the driver with:

Further, in order for autosuspend to be more help than harm, it appears that the USB device's driver needs to support autosuspend. Hence all the posts- yours' included- seeking to disable the "feature".

I faced the same problem with my HP pavilion x360 (dual boot with windows 10). All I did was to log into windows 10 and update my bluetooth driver from HP website and then when I restarted the system to Ubuntu 20.04 my problem was fixed.

Once you have downloaded your new driver, you'll need to install it. In Windows, use a built-in utility called Device Manager, which allows you to see all of the devices recognized by your system, and the drivers associated with them.
