Hi,

Thanks for the suggestions. I had small amount of time so I enabled the debug
info and it seems that it does have some successful suspend resume cycles. All
the debug info also made me realise that the Steam flatpak wakes up (all?) the
USB controllers and then they autosuspend again, which is what was usually
triggering the bug on my system.

I did manage to open and close Steam without any issue maybe 10 or so times,
then I unbound and rebound the controller and it immediately failed on the next
Steam launch. So I suppose sometimes the controller just behaves (totally?)
fine, and other times fails easily?

> Passing quirks=0x20000 parameter to xhci_hcd increases the timeout

I'll give it a try and report back when I have some time, hopefully at the
weekend

> Does it also show up when suspending the system?

I hadn't noticed it, but I'd only been able to test it on boots where it didn't
immediately get killed by Steam autolaunching. I'll give it a try again, and
also try unbinding then binding the controller again since that seemed to get
the controller to fail on the next suspend / resume cycle (Steam launch) when
it was behaving.

> Are you able to compile and test patches?

Yep
