Harmony 520 remote will not show USB Connected when I plug it into the USB plug. I have updated the software to the latest version on my pc running XP. I have also tried all of the plugs in the front and back. I have tried three different cables. I have also tried pulling the batteries out and puting them back in. Any help would be appreciated!' tks, matt

I would advise you complete the following troubleshooting steps:

1) Remove the battery from the Harmony Remote for 10 seconds and reinsert it. If this does not resolve the issue, please continue troubleshooting.
2) Ensure you have the latest version of the Harmony Remote Software (7.6).
3) Update the firmware on the Harmony Remote. The following link shows how to complete this task:

4) Try putting the Harmony Remote in safe mode and complete the firmware update again. The following are the steps to accomplish this:
a) Remove the battery from the Harmony Remote.
b) Press and hold the power button while reinserting the battery into the Harmony Remote.
c) To get out of safe mode, remove the battery for 10 seconds and reinsert it into the Harmony Remote.
If this does not resolve the issue, contact Logitech and let them know you did all these steps!

Have a nice day! =)

Please apply the following troubleshooting steps to get the LCD screen issue resolved:

1- Remove the battery from the Harmony Remote for 10 seconds and insert it back in, and test the remote to see if the screen is displayed properly. If this does not fix the issue, please proceed with the following steps.

2- Make sure you have the latest Logitech Harmony Software (version 7.6.0) installed on your computer.

3- Connect your Harmony Remote to the computer. Run the Logitech Harmony Remote software on the computer and Login to your account.

4- Click on the "Downloads" button at the top and select "Firmware"

5- Remote will go through the firmware update, which will put the Harmony Remote back to Factory Default with the most updated firmware. Then software will ask you to select "Yes" to update the remote and click on "Next" to do a remote update, which will take the information on your account with your Devices and Activities and bring them into the Harmony Remote.

6- If this Firmware Update process does not fix the LCD screen issue, try doing a Firmware Update in "Safe Mode". To do this; remove the battery from the remote, press and hold the "Off" button on the top of the Harmony Remote and insert the battery back in to the Harmony Remote. Screen will display "Safe Mode" and then please follow the steps 3 through 5 again.

If this doesnt fix the problem i suggest you contact logitech. when contacting them, do not tell them your son spit soda on it:

Cases not covered under warranty:

Try a different cable, any standard mini usb cable will work. When it asks to press a button on the remote unplug the remote and plug it back in and it should pick it up right away.

I have had similar quirks with harmony remotes be never had one I couldn't connect too.

Failing that harmony has an excellent tech support service, it could be a remote problem.

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.

reinstall your software and connect in the back of the computer to a usb port directly connected to the motherboard
