Solved I am dual booting from the same hdd windows 7 and Fedora 21.

May 8, 2015 at 19:01:29
Specs: Windows 7, CPU: Intel Core Duo E7500,. RAM 4 GBytes
The problem is that my USB HID compliant mouse works ok on windows but freezes intermittently on my fedora. This happens very frequently, if I unplug it and plug it back in again it works, but this happens all the time and is very annoying and hindering my progress on an online course. I've done numerous searches but find no solutions.
I would greatly appreciate any advice on solving this problem. Many Thanks!

You may need to turn on support for the HID.

Sorry for the delay in replying!

I read the article on WWW.linux-usb.org and it makes very interesting reading.
However, I think those instructions refer to compiling and installing your own version of kernel and mine is a distribution one.

After many hours of online research I was unable to find a specific solution to this problem, probably a bug.

The output from 'dmesg' showed that the mouse interrupts always ocurred
after this message:

'perf interrupt took too long (2511 > 2500), lowering
kernel.perf_event_max_sample_rate to 50000'.

I did find a workaround by switching distro. I ditched fedora 21 workstation (nothing against fedora - it's just more suited for more advanced linux users) and changed to linux mint 17.1. What a difference, no more mouse freezes and everything works like a charm, brilliant os, very happy with it.

Now, I can get on with my studying.

Anyway, thank a lost for your help
