Hi Greg,
We (Fedora) have been receiving multiple reports about USB devices stopping working starting with 5.14.14 .
An Arch Linux user has found that reverting the first 2 patches from this series: https://lore.kernel.org/all/20210909064200.16216-1-kishon@ti.com/
Fixes things (the 3th patch is just some mostly unrelated refactoring/cleanup).
See here for the Arch-linux discussion surrounding this: https://bbs.archlinux.org/viewtopic.php?pid=2000956#p2000956
And here are 2 Fedora bug reports of Fedora users being unable to use their machines due their mouse + kbd not working:

Can we get this patch-series reverted from the 5.14.y releases please ?
Sure,
Thanks.
but can you also submit patches to get into 5.15.y and 5.16-rc1 that revert these changes as they should still be an issue there, right?
Yes I assume this is still an issue there too, but I was hoping that Kishon can take a look and maybe actually fix things, since just reverting presumably regresses whatever these patches were addressing.
We've aprox 1-3 weeks before distros like Arch and Linux will switch to 5.15.y kernels. So we have some time to come up with a fix there, where as for 5.14.y this is hitting users now.
I've reverted them from all stable kernels for now. Unless this gets figured out by 5.16-rc1, I will revert it from there then as well.
thanks,
