I just plugged Logitech speakers into my desktop. Do I need to download software for them to work?

no you dont need to download anything on your mac computer.

there are two ports in mac computer one is for mic and one is for your speakers. make sure your are connecting to the right port.

and please check/change the powerpoint of your speakers.

then check it should work now.

Visit the Logitech website and browse the photo gallery for your model and click on the photo to navigate to the support page.
Note - Older models on page 2 - look for the link at the bottom right of page 1 and click on it "Still can't find your product?"

In addition to the Logitech installer you will need to check the support software - Microsoft DirectX . This comes pre-loaded on most Windows computers but has to be updated - I am currently on version 11
To start the DirectX Diagnostic Tool, click 'Start', click 'Run', type dxdiag in the Open box, and then click OK
Run through the tabs checking the 'notes' windows for information
The version will be shown on the 'Systems' tab

Procedure to re-install Logitech software
Close all programs while uninstalling - downloading and uploading software
Disconnect your webcam
Uninstall the current webcam software on your computer
Restart computer
Download the Installation package from Logitech
Run the installer and choose your options during the installation - You may not want Logitech Chat but the Desktop icon for the webcam toolbar is a must.
Connect your webcam when prompted.

Test your webcam here to make sure it broadcasts ok - Hit 'Allow' in the top window and check your cam in the left hand panel.

go to logitech.com support plug in your model number and download the setpoint software from logitech for your particular product. Should then work fine.

You may need to install the audio drivers for those systems. If the sound is built onto the mainboard, you'll need the motherboard model number to help locate the drivers online. You can look for them yourself through a search engine, or if you'd like, get back to me with the model numbers of the motherboards, and I will locate your drivers. The model number of the motherboard should be printed directly on the motherboard itself.

When I bought my s510 recently I couldn't use the function keys even with the software that came with the keyboard and mouse.

I had to actually download new logitech software for the s510 which allowed me to use the function/extra keys.

Navigate to:
http://www.logitech.com/index.cfm/keyboards/keyboard_mice_combos/devices/145&cl=US,EN

On the right hand side of the screen you will see 'Support Center' below it click 'Downloads,'
From there you can choose your OS w98 and language and download the software you need to get your keyboard working the way it should.

The R10 speakers are analog speaker drivers are not needed, you may need drivers for your sound card-- quick test plug a headset into the green port on the back of your computer. if there is sound coming thru then the sound card is fine and you need to make sure your connection are correct. if no sound, plug the headset into the front ports for headphones. if sound is coming thru there but not in back the sound card needs replacement the port is bad.
