Question about Logitech Harmony 628 LCD Remote Control

Logitech Harmony Remote

My computer (Macintosh, running OSX 10.4.6) does not recognize the Harmony Remote when I plug it in via the USB cable. Everything worked fine ~6 months ago when I first set the device up, but now that I'm trying to change the configuration I can't even get the computer to recognize that the remote is plugged in. Thoughts?

Re: Logitech Harmony Remote

Check the batteries are OK Uninstall it's software, reboot and reinstall it. See if there's a return to default option in the software. You may have mucked things up when you tried changing the configuration. Sorry I can't give more advice I don't know the hardware at all. BMW

Harmony One USB Connection Problem on Vista PC

HI. So there are a couple of things you will have to ensure for the connectivity to be successful.

1. You are not connected to the internet via a router

2. You are not on a wireless network

3. Any firewalls on your computer are disabled

4. Your USB cable and port are good, and the remote is not connected to a USB hub but right into the compter.

Now, please do the following:

1. Uninstall the software

2. Download it again at
3. Install
4. In your computer's add/remove programs, uninstall the Logitech Desktop Messenger

5. Take out the battery, press and hold the "OFF" button, and re-insert it. The remote will display "Safe Mode"

6. Connect your remote and log in to your account

7. Click "Downloads" at the top and select "Firmware". The firmware on the remote will update.

8. Click "Replace Remote" to conduct a connectivity check.

9. Update the remote.

That should get the remote working. :)

My harmony 1000 remote is not recognized by my mac computer

I had the same problem today on PC with the Harmony 1000. I noticed on the USB cable that mine came with it had a warning red icon (!). 1. install software then 2. plug in USB...

I didn't see this and I installed my software whilst the device was in the charging cradle with the USB cable plugged into my PC.

Before the software was installed I noticed the USB icon next to the Help on the remote screen, this dissappeared when the software finished installing the software and drivers.

I removed the remote from the cradle, pulled the battery out, unplugged the USB from the remote and computer, restarted my PC, powered on the remote, started the software on the PC and then plugged the USB into the remote and then the PC.. it was then recognized.

The display on my Logitech Harmony 520 has gone out. The remote lights up and controls everything but you cant see any of the letters on the screen to know what you are selecting.

Try opening the Logitech Harmony remote software on your computer, then log in. Update the firmware. Don't plug the USB cable into the remote until you are requested to by the program. It should recognize the remote and let you know, even if the screen isn't showing anything. Try to update and see if this helps.

No idea how to setup

You need a computer with Internet and a USB cable. Download and install the software from Logitech's website, plug in the remote so the software recognizes it and from there it is about as simple as it could be.

Can't connect to usb port

Hi all! I had the exact same problem - the remote recognized the USB connection but my computer (MacBook with Leopard) / Logitech software did not.  I took the advice of  bfuzcsvxvgk  and it worked like a charm.  I wasn't sure what the "Home" folder that he or she referred was, so instead I entered "Logitech" into the Spotlight finder and the Logitech folder came up.  There was only one file (usblancognac.cmd) in the folder and I deleted it. After that I reopened the Harmony Remote software and it opened! THANK YOU THANK YOU THANK YOU!  Hope this helps if you are having problems!
