How to search Linux Kernel changelogs? (USB disconnect problem)

[Omer Zak]

During the last several months, I was having a problem of USB mouse
disconnecting and reconnecting very often in my Linux system (Debian
Wheezy, kernels 3.16.0-4-amd64 and 4.2.0-0.bpo.1-amd64). Recently a
similar problem started to affect also my printer.

Hardware problems were ruled out yesterday in the computer repair lab.

I found some information which suggested that it has to do with USB
power control, and that there are several problems with USB handling in
general.

I also saw that other people complain about similar problems, often
without a solution to their problems.

So I wanted to search the Linux Kernel changelogs for any recent changes
in the USB subsystem.

Unfortunately I found no such search function.
https://www.kernel.org/pub/linux/kernel/ has all changelogs in its
subdirectories but no search function.
The search function in http://kernelnewbies.org/LinuxChanges is broken -
I get Web searches even when I choose "This site".

What do you do when you need to search Linux kernel changesets for
relevant changes?

If no better solution, you can clone the kernel git repo and use git to
search there.

I had a "problem" with tlp & powertop when i tried to used this tools to
configure my system (laptop) to conserve energy,
I enabled all tunable options, and I started to experience smiler symptom
as you describe above,
where my mouse will suddenly stop working, and my disk was contently
sniping down and that created lags when I was switching tabs in the browser.

At your hint, I have installed powertop.
I did not find a tip in Debian, but there is a tiptop command in my
system.
How can they help me diagnose USB problems?
