Keyboards and Keyboard/Mice Combo Sets

[Lepryy]

Ok so a while back I bought this set (MK520 I think...) and it took me about two days of extreme frustration to get the thing working. But I finally did get it working, and no matter what USB port I used (3.0 and the 2.0) it would work fine with no problems at all. Then I installed Windows 8 Consumer Preview. Still, no problems, it worked on any USB port I put it in. THEN, I went back to Windows 7 Ultimate because WIndows 8 CP is way way too buggy for me right now. So, here I am on Windows 7 Ultimate (64 bit) again, but the problem is, it only works if I have it in the 2.0 port, which is fine, but see I have one USB 2.0 port and two USB 3.0 ports, and I need my headset (requires a 2.0 port) AND my keyboard/mouse receiver plugged in at the same time. But when I use a 3.0 port with this thing, nothing happens, like my PC doesnt even acknowledge I have it plugged in whatsoever. And yes, I have tried using the Unifying Software to no avail. Please help because I need to get this working on a 3.0 port ASAP.

Thanks!

P.S. I'm pretty sure it would have something to do with a driver I need to have installed, maybe?

Does anything work in the USB 3 ports? I find that these are sensitive to their own drivers, let alone anything you plug into them.

When you went back to Windows 7, did it involve reinstalling or anything drastic like that? If so, you may need to get the USB 3 drivers for the motherboard, or whatever you use to provide those ports. (I have on board and PCI sources for mine.)

If it is a Logitech issue, then it might be worth going into device manager and uninstalling "disconnected" USB devices. With the receiver detached. The get Windows to recognise the receiver all over again.

My problem is quite similar, only difference: I did not install Windows 8.

The receiver works fine as long it is connected directly to the USB 3.0 port. As soon I connect something different dirctly next to it or better as soon I connect USB 3.0 stick next to it it stops working.

connecting it through a passive USB 2.0 Hub at the same port works fine...

Guess some kind of initialisation or timing problem.

I would highly appreciate if this gets fixed very soon!!!!
