Hello Injoel,
Various Logitech USB cameras interfere with the proper operation of USB audio or MIDI devices which use the USB Audio Codec. This is because when the camera driver is installed, the computer tries to use it for all USB audio or MIDI devices. This driver is also not properly uninstalled if the Logitech Software is uninstalled by normal means.
The following download attached to this email contains a registry script which will remove the problematic file. Simply unzip the file and double click the file titled "LowerFilters_remove.reg." You will likely be asked by your computer whether or not to allow the action. When asked, choose "Allow"
If, for any reason, you are unable to use the script attached to this email, the following procedure will guide you through determining if you have this problematic driver installed, and will show you how to manually remove it.
1. Connect the USB device which is not working correctly.
2. Right+Click the My Computer icon on the desktop and choose "Properties".
3. In the window that opens, select the "Hardware" tab.
4. Click the button labeled "Device Manager".
5. In the list that is presented, locate the heading "Sound, video and game controllers".
6. If there is a "+" to the left of the words "Sound, video and game controllers", click the "+".
This will expand the heading so that all Sound, video and game controllers that are connected to your computer will be visible.
7. Right+Click the device titled "USB Audio Device" and select "Properties"
8. In the window that opens, select the "Driver" tab.
9. Click the button labeled "Driver Details".

C:\\WINDOWS\system32\drivers\ksproxy.sys
C:\\WINDOWS\system32\drivers\ksuser.sys
C:\\WINDOWS\system32\drivers\wdmaud.sys
11. If there are more than 8 items in your own list, find out which one is not in the above list, and write it down.
The Logitech driver may appear with the same name as the one pictured below:
