[SOLVED] Cannot connect Bluetooth headphones via dongle via USB hub

I have a powered USB switch, which has a Bluetooth dongle plugged in, and trying to connect my headphones to it.
The headphones don't connect, but when I plug the dongle directly without USB hub, it works.

I heard that typically that happens when USB hub doesn't have enough power, but:
- It does work when I plug it to a different machine (which happens to run Ubuntu)
- It doesn't work even when it's the only device connected to the USB hub (and I'm pretty sure the hub should survive that, it's 13-port i-Tec chargehub with 60W own power supply)
- It did work before (on the same computer with arch linux) until I broke it somehow by trying repeatedly pair and unpair the device.

When I insert the dongle, bluetooth-manager sees the dongle. When I try to connect the headphones, error "Connection Failed: Resource Not Ready".

From command line:

~ $ bluetoothctl connect 14:3F:A6:15:05:26

Re: [SOLVED] Cannot connect Bluetooth headphones via dongle via USB hub

nuke /var/lib/bluetooth and see if you can pair again

Re: [SOLVED] Cannot connect Bluetooth headphones via dongle via USB hub

I've just tried that. Here is what happens:

- The dongle doesn't seem to power up (it doesn't blink blue when I start the search as it usually is)
- The "search" button in blueman-manager cannot find any devices nearby.
- bluetoothd still seems to be able to see the dongle somehow. At least it appears in the list of bluetooth adapters when I plug it in.

That's even worse than in worse before, I'm moderately sure that I was able to start pairing earlier but couldn't complete (also after nuking /var/lib/bluetooth, I actually tried that earlier).

As before, works fine when not having the USB hub in between.

Re: [SOLVED] Cannot connect Bluetooth headphones via dongle via USB hub

Just an update,

as written here: https://bbs.archlinux.org/viewtopic.php?id=268281, it turned out to be a kernel issue.

When I reboot to LTS kernel, everything works fine.

Even when I reboot to the latest kernel after bluetooth was powered up in LTS kernel, it still works fine.

But if I unplug the dongle and plug it back, it cannot be powered up again.

Re: [SOLVED] Cannot connect Bluetooth headphones via dongle via USB hub

Found this https://bugzilla.kernel.org/show_bug.cgi?id=213369 kernel bug report.

Downgraded bluez to 5.55-3 as suggested there, and now bluetooth dongle works even with the latest kernel.
