Yes. USB_AUTOSUSPEND module is removed now. You should instead use

Maybe you should consider removing its config file as
well? Anyway, I have added the usb id to the blacklist.
Problem solved.
I'm glad that solved your problem. I am very broke right now. So that
was the quick fix I did because of the number of bug reports. We should
have a way to handle the removal of that stale config file.
But in the office we have tons of different mice. Its
pretty painful having to list every potential mouse model
on every laptop. Turning off autosuspend for all usb is
probably not the right way, either.
Is there *any* optical mouse that does not turn off its
LED in autosuspend mode, or are they all flaky? I would
prefer a more reasonable default for this case.
I really do not have an answer to this question. This is perhaps
something the kernel devs (or the hardware devs) should answer.
There are other ways to blacklist. Like blacklisting the modules. You
may want to explore those options. Otherwise, if you have an opinion,
let me know. I will consider it.
The thing about USB power saving is that it is a tradeoff in between how
much flexibility you want, and how much power you'd like to save.
