Subject: [5.12.X] USB controller committing suicide

Hi all,

recently (most probably since switching to 5.12.N) I see USB controller
suicides, with the effect that after that:
$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


This is:
* linux 5.12.X (self compiled)
* Debian/unstable

The dmesg contains the following:
[32154.046627] usb 1-6.1.3.3: Manufacturer: Generic

[39567.823671] usb 1-6.4: USB disconnect, device number 6

Looking at the systemlog I see only one more line (between the rest of
the noise):
May 13 09:57:41 bulldog systemd-udevd[669]: 1-6.1.3.3: Worker [1112921] processing SEQNUM=3950 is taking a long time


My questions are:
* is there a way to get the USB devices back (I can log in via ssh)
* how can I debug this?
* known issue?

Thanks and all the best

Norbert
