Usb Extender for a mouse

Hi guys so this is my question;

Will a usb  extension cable will add any latency to my mouse/keyboard?

I really can´t reach my pc with the original. I´ve seen on other sites that an usb extension to a usb hub and then to the mouse could work.

Any ideas?

It should unless you are planning on an insanely large extension, but a 1 meter extension cable shouldn't increase latency

The problem is that i need it to be 4.5m long because i am making a setup from my htpc to a monitor sitting near it. I read that for those leghts the timings for the actuals mouse cord lenght get messed up.

I JUST WANNA GAME WITHOUT ANY LAG ): 

It should be fine.  5m is not that long and it should not add any latency.  I would imagine that you would need a very long extension like 50m to see any sort of difference. 

Thanks, I just wanted to make sure that by buying a wired mouse with an extension over a wireless mouse i wasnt going to end up with even more latency than with the wireless..

Btw what video input would you choose for the same lenght; display port, dvi or hdmi

I thought it wouldnt matter because they all carry a digital signal right?

It doesn't matter what you choose to use, you can get all 3 in 6 meter lengths

Ok, thanks for the help.
