Hello,

My bluetooth usb-stick worked fine with kernel up to 3.19. With 4.x there is no hci device found.

sudo hciconfig hci0 up

rfkill list

Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN

Is this a regression. Or does it work in different way with 4.x?

Regards,

Norbert

Is this a regression. Or does it work in different way with 4.x?

your controller has this issue:

< HCI Command: Read Stored Link Key (0x03|0x000d) plen 7

When this command fails for whatever reason, the power on procedure fails. It is indicated that this command is supported, but it seems that this actually not fully true.

Please report the section from /sys/kernel/debug/usb/devices that corresponds to your device.

Hi Norbert,

Is it possible to add a quirk or something else?

This was reported in the kernel.org bug tracker as well. Could you try the patch proposal that I've attached there:

https://bugzilla.kernel.org/show_bug.cgi?id=103451

In the bug report it's just a single patch but I'll probably split it into two for the final upstream submission.
