Question: My USB Channel or other USB hardware isn't recognized, what should I do?
Question: When connecting the USB, I receive a message that the maxmimum services or end points are reached. How can I fix this?
Answer: Link: please follow the steps at this link

In case one or more USB channels or other hardware isn't recognized by the compputer and on the mixing consoles the USB input leds are not lighting.

First take a look at these steps.

* Be sure that your USB cable has a maximum length of 1,8 meters (5,9 ft).
* Connect your mixing console to a USB port directly at the mainboard of your computer. So no internal cables are used.
* Do not connect the mixing console trough a USB Hub or a USB Extender.

This way the USB connection has enough bandwidth to use the USB Audio codecs and USB hardware for Meter software and controls.
Inside the mixing console is a USB Hub that can handle the bandwidth this hardware needs.

For customers that receive a operating system message that the maximum end points or services are reached.
In some computers the manufacturers have chosen to use xHCI USB 3.0 ports.
This actually means that they combined the hardware of 2 USB 2.0 ports to reach higher speeds like the USB 3.0.
Combining these ports means that they need to share the amount of end ports that all USB equipment has.

When detecting the connected equipment the Operating System fills it's list of end points for that port until the maximum is reached.
With each Audio Codec needing multiple end points as well as the used hardware for controls and meter software, one mixing console can take all the end ports of a port.

This can be fixed by setting the USB ports to work as non xHCI ports (USB 2.0) in the BIOS configuration of your computer.
Another option is to use a USB2.0 card that is added to the computers ports.

Then you can try the following procedure.

* Disconnect your Airence from the PC. (USB Cable)
* Download USB Deview and run it. http://www.nirsoft.net/utils/usb_devices_view.html
* Remove all devices with the name “USB AUDIO CODEC” in it with the trashcan.
* Connect your Airence with the standard USB cable.
* Now, wait patiently till Windows will recognize all the USB codes again.
* You should see all the usb audio codecs come up in usb deview again.
* If everything went fine all the four LEDs should be turned on. If not, something went wrong.
* Close USB Deview

If this does not work, please consult the factory.
