USB Device Tree Viewer 3.8.9 instal the new version for windows

So I’m trying to give an idea on what’s going on. This post goes down to the gory details, partly for the sake of quick diagnostics in the future, and partly because Bluetooth tends to be a mystery thing. Something that is worked around with a hush-hush fix in the driver for Windows, but the Linux driver doesn’t do the same. My guess is that due to a bug, the chip sometimes needs some kind of tickle on shutdown or when starting, or Bluetooth is lost. Or turning Bluetooth off and on again with the BIOS. However there are also some rumors on the web, which I can’t confirm, about Bluetooth coming back to life after loading Windows on the same computer.

Powering off the computer this way is what solved it for me. The device probably continues to get power from the motherboard when in computer is off by virtue of its own power control.

Just powering off the computer the fine way isn’t enough. I’ll jump to the spoiler: If you happen to have a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter on your machine, never just reboot the machine: Shut down the computer completely, and disconnect main power for a minute or so with the power supply’s switch. Prior to this mishap, my Atheros QCA6174 had worked flawlessly and reliably for several months, both as a Wifi adapter and a Bluetooth adapter.įor the record, I have a Linux Mint 19 Tara machine with 4.15.0-20-generic kernel on a X299 AORUS Gaming 7 motherboard, running in 64 bit mode of course. There was simply no Bluetooth device in the system to talk to.

It took some time to figure out that the problem wasn’t with the Cinnamon 3.8.9 fancy stuff, nor the DBus interface, which produced error messages.

Having rebooted my computer after a few months of continuous operation, I suddenly failed to use my Bluetooth headphones. Posted Under: bluetooth, Linux, Linux kernel, USB, wifi When Bluetooth goes poof This post was written by eli on July 21, 2019
