Logitech Unifying Receiver - Interference? Speakers?

by measureless / August 23, 2012 12:55 AM PDT

I've looked for help with this issue directly with Logitech but their customer support is... not so great.

I recently switched to a desktop from my old laptop. I have a wireless keyboard (wireless solar) and mouse (M510) from Logitech that are using the same Unifying Receiver. Setpoint is installed and it works fine... until I try to connect speakers to my machine.

I originally had a set of Logitech speakers (X-140) that I had been using for a Xbox+monitor setup and figured they would be fine. Except any time I had the speakers plugged into the computer, my keyboard and mouse would stop responding for a few seconds every fifteen minutes or so. And since this is a gaming machine, that was a big deal.

Moving the speakers further away from the computer seemed to help but not by much. Eventually I replaced the speakers with cheap $15 ones and, again, it reduced the occurrence but did not resolve it.

The only time I can play anything now is by unplugging my speakers altogether and using headphones. And I hate headphones.

I really, really like my keyboard and would like to keep using it but this just has to stop. I'm open to ideas that maybe, perhaps, it isn't speaker interference but then... the problem stops when I remove them.

I have had no luck finding anyone else with this problem, though. Are there speakers out there that will not do this? Is there some other way around it?

Speaker problems

Have you ever tried using powered USB input speakers? From the description of the issue I suppose it could an interference issue as you stated. In a normal stereo system such issues are many times related to poor sheilding (cables) or a bad ground connection. I use Logitech systems on two desktops, including wireless keyboard/mouse. My speakers are powered USB input and they work very well.

USB-powered

Yes, the original Logitech speakers had a giant brick of a power supply thing that blocked the entire end of my power strip but the new cheap ones are USB.

Did you try?

I had a similar problem last year so I found an USB extension cord and placed the unifying receiver on that and then up on the desktop (the table!) so the keyboard and mouse were inches away. What ever the problem was, it's cured.

That seems strangely counter-intuitive but I will try it!

Why so?

Moving the receiver closer to the devices seems to help in such cases. If I leave the receiver on the desktop it's farther away.

More advice? Use the rear USB ports for such things.

I see your point, that moving the receiver next to the devices shoulder help, but I just figured doing so is also moving it closer to the speakers. It's worth a shot as soon as I can find someplace near me that sells USB extension cords for less than $30 (thanks, Source, I really think that is worth that much. Ugh).

At amazon.com a few bucks.
