Wireless mouse reduced range..

[zentili]

hi all! I recently built this system:

 

-Gigabyte GA Z87-HD3

-Intel Core i7-4770K

-Ram Corsair Vengeance 1600 Mhz 16GB

-Segate 3,5'' Hard Disk (1TB)

-For the moment I am using integrated Intel graphics (the HD4600), I will switch to GTX 770 very soon.

-Clover EFI

-PJALM DSDT Patch for my mobo

-Mavericks 10.9.3

 

Everything working. 

 

The only issue i am having is a strange one: I use a logitech wireless mouse and keyboard (they have their own usb wireless receiver) and they "work" but their range of action is very much reduced on this system and i have to keep them very close to their receivers to get them working smoothly. I have tested theese devices on windows, same computer, and they have much more range without any driver installed or anything. The same happens if i plug them on my laptop with Mavericks 10.9.3: they get their full range of action. I didn't find out what could cause this issue.. maybe something wrong with combination of Haswell/USB 3.0/Anything? 

 

I am planning to buy a bluetooth receiver with new bluetooth mouse and keyboard but i am afraid this problem will affect that too.. 

 

Any idea, please answer!
