Description dilipkonline 2021-02-05 00:26:55 UTC

Using fedora 33 and fedora repos only for upgrades

Ever since I moved to 5.10.x series the bluetooth had stopped working.

From journalctl I get the following error,

kernel: usb 1-1.1: new full-speed USB device number 7 using ehci-pci
kernel: usb 1-1.1: New USB device found, idVendor=13d3, idProduct=3362, bcdDevice= 0.02
kernel: usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
kernel: usb 1-1.1: Product: Bluetooth USB Host Controller
kernel: usb 1-1.1: Manufacturer: Atheros Communications
kernel: usb 1-1.1: SerialNumber: Alaska Day 2006
kernel: Bluetooth: hci0: don't support firmware rome 0x1020200


If I boot to previous kernel version 5.9.x, it works out of the box.

I have tested this patch and works using latest kernel source:

This is the same as https://bugzilla.kernel.org/show_bug.cgi?id=210681?

Comment 8 dilipkonline 2021-02-14 05:52:12 UTC

Thanks Hui and Helber,
I am still waiting for the Fedora team to push the kernel package as I do not wish to perform the manual compilation and wish to stick on with the distro repo.
I guess 5.11 release will have this fixed.

Comment 9 dilipkonline 2021-04-03 11:19:55 UTC

This is fixed now. Using kernel version - 5.10.22-200.fc33.x86_64 without any issues. Thank you all.
