Will not suspend, if I have Native Instruments Audio Kontrol 1 connected

[Jarno Suni]

$ lsusb

Bus 003 Device 002: ID 17cc:0815 Native Instruments Audio Kontrol 1
..

If I have the device connected when I choose suspend to RAM then display blanks, suspend fails and system does not respond to any user input except power button.

Workaround:
Unbind "usb" driver from the device manually before suspending. That can be done to work automatically by a special script in /lib/systemd/system-sleep. Unbinding has the side effect that a new sink is created on resume from suspend.

This change was made by a bot.

Can you attach `journalctl -b -1 -k` at the next boot of freeze?

[Kai-Heng Feng (kaihengfeng)]

Sorry for missing your reply at 2019.

Was the log collected with suspend attempts?

Can you please boot with kernel parameter "usbcore.dyndbg log_buf_len=16M", reproduce the issue and attach `journalctl -b -1 -k`?

[Kai-Heng Feng (kaihengfeng)]

Oh and don't forget to try mainline kernel first, there are some suspend related fixes:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc4/amd64/

[Jarno Suni (jarnos)]

Booting mainline kernel did not help. Then I added the kernel parameters for it.

[Kai-Heng Feng (kaihengfeng)]

Ok, it's more likely to be a bug in the caiaq driver.

[Jarno Suni (jarnos)]

Oh, do I have to make a different bug report or address this one to another package (which one)?

[Kai-Heng Feng (kaihengfeng)]

No, linux is the correct package. And I just subscribe the sound maintainer to this bug.

Still present in 5.13.0-27-generic.
