-In case one or more USB channels or other hardware are not recognized by the compputer and on the mixing consoles the USB input leds are not lighting.\\
+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 be sure that your USB cable has a maximum length of 1,8 meters (5,9 ft).\\
+=====Important when you use USB audio equipment:=====
+\\
-Then you can try the following procedure\\
+{{ :usbnotworking:usbcable.jpg?direct&200 |}}
+* Be sure that your USB cable is a High speed USB 2.0 cable and has a maximum length of 1,8 meters (5,9 ft).\\
-* Disconnect your Airence from the PC. (USB Cable)\\
+\\
-* Download USB Deview and run it.\\
+* It can help to replace the cable as a good connection is really important with the high bandwidth the mixer uses.\\

+\\
+{{ :usbnotworking:connect.jpg?direct&400 |}}
+* Connect your mixing console to a USB port directly at the mainboard of your computer. So no internal cables are used.\\
+\\
+{{ :usbnotworking:usbexthub.png?direct&400 |}}
+* 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.\\
+\\

+\\
+=====I receive messages that the maximum end points or services are reached:=====
+\\
+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.\\
+**__Be carefull to only change USB settings! Changing other settings can harm your computer!__**\\
+**__D&R is not responsible for changing the wrong settings!__**\\
+Another option is to use a USB2.0 card that is added to the computers ports.\\

+=====Windows 10 Update and changed settings=====
+\\
+The rollout of Windows 10 updates can also affect the working of your mixing console.\\
+Due to privacy and safety rules Microsoft is changing the way that Windows 10 works with audio equipment.\\
+\\
+For example: Windows mutes the Microphone channels to be sure nobody can hack your system and listen to what you are saying.\\
+It can also change levels, disables inputs or set the default settings of audio devices.\\
+\\
+When you enter the Sound settings everything seems to be as you set it up before the update.\\
+Unfortunatly the settings are changed in the background and the settings shown aren't changed along.\\
+\\
+To fix this change each setting and change them back to the desired setting to make it actual again.\\
+\\
+-----
+\\
+=====My USB devices are mixed up:=====
+\\
+Then you can try the following procedure.\\
+\\
+{{ :usbnotworking:usbdeview.png?direct&800 |}}
+\\
+* Disconnect your mixer 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.\\
+* Connect your D&R mixer 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\\

+=====Tips and tricks:=====
+\\
+We also have some other usefull tricks to get your USB device to work.\\
+* Method 1: Unplug the computer and mixer from the power supply and re plug.\\
+The most recent computers aren't really going off when you shut down, the mainboard of the computer still have some power lines connected for the stand-by situation.\\
+To reset the hardware completely it can help to disconnect the computer and mixer from the power outlet.\\
+{{ :usbnotworking:unknownusbdevice-thumb.jpg?direct |}}
+* Method 2: Update the Device driver.\\
+Go to your __control panel__ and then to __device manager__.\\
+Find the __Unknown Device__ and click on Properties, go to the driver tab and click __Update Driver__..\\
+{{ :usbnotworking:update-driver.jpg?direct |}}
+* Method 3: Disconnect all USB devices and restart your computer.\\
+Disconnecting all USB devices and restarting and reconnecting will force the computer to re-detect USB devices.\\
+Connecting on different ports can also force the computer to detect in a different sequence.\\
+* Method 4: USB Root Hub power management.\\
+In the __Device Manager__ expand __Universal Serial Bus Controllers__, right click on __USB Root Hub__ and __Properties__.\\
+{{ :usbnotworking:usb-root-hub.jpg?direct |}}
+Go to the __Power Management__ tab and uncheck __Allow the computer to turn of this device to save power__ checkbox.\\
+{{ :usbnotworking:usb-root-hub-prop.jpg?direct |}}
+This setting has to be done for each __root hub__, on the computers mainboard are the USB connectors also connected to high speed USB hubs.\\
+These USB hubs each have enough bandwidth to connect a D&R mixer.\\
+Connecting a external Hub will devide the bandwidth over more ports and causing the bandwidth being to low.\\
+Now restart your computer and reconnect the usb device, when the computer recognizes the USB device you can leave this settings as made.\\
+When it still doesn't recognize the USB device reverse this setting for every hub and reboot.\\
+* Method 5: Update Generic USB hub drivers.\\
+In the __Device Manager__ expand __Universal Serial Bus Controllers__, right click on __USB Root Hub__, choose __Update Driver Software__ for each USB hub.\\
+When you downloaded the drivers from the manufacturers website select __Browse my computer for driver software__.\\
+Now browse to the folder where you downloaded the driver and install.\\
+{{ :usbnotworking:update-generic-usb-hub.jpg?direct |}}
+* Method 8: Uninstall USB Devices.\\
+Be carefull with this option, when your Keyboard and Mouse are also connected by USB you can end up with an computer that can't be controlled.\\
+In the __Device Manager__ right click on each __USB device__ and select __Uninstall__.\\
+This can also be done with __USB deview__ that is mentioned before.\\
+__USB deview__ will also show the __USB devices__ that are not connected (hidden devices), you can also uninstall these.\\
+Rebooting your computer will force to re-detect all the devices.\\
+{{ :usbnotworking:uninstall-usb.jpg?direct |}}
+* Method 9: An other way to uninstall hidden devices.\\
+To view hidden devices in the __Device Manager__ you'll first have to enter the next commands in the __Command Prompt__.\\
+set DEVMGR_SHOW_DETAILS=1\\
+set DEVMGR_SHOW_NONPRESENT_DEVICES=1\\
+start devmgmt.msc\\
+When the __Device Manager__ is started click __View__ and __Show hidden devices__.\\
+Expand __Imaging Devices__, __Universal Serial Bus Controlles__ and __Unknown Devices__.\\
+You can now __Uninstall__ the greyed out devices.\\

+# Method 10: How to disable USB selective suspend.\\
+If you're having connectivity issues with USB peripherals on Windows 10, use these steps to disable the USB selective suspend feature.\\
+\\
+Important: It's only recommended that you change this particular setting when you're experiencing problems with a USB device. Otherwise, you should leave the option enabled.\\
+\\
+-Open Control Panel.\\
+-Click on Hardware and Sound.\\
+-Click on Power Options.\\
+-Under "Preferred plan," click the Change plan settings link for the plan you're currently using. (If you change the settings on the power plan that isn't active, this won't work.)\\
+{{:usbnotworking:selsuspend1.jpg?600|}}\\
+-Click the Change advanced power settings link.\\
+{{:usbnotworking:selsuspend2.jpg?600|}}\\
+-Expand USB settings.\\
+-Expand USB selective suspend setting.\\
+-Select Disabled from the drop-down menu.\\
+{{:usbnotworking:selsuspend3.jpg?300|}}\\
+-Click Apply.\\
+-Click OK.\\
+\\
+If you're changing the settings on a laptop or tablet, you'll see two options: On Battery and Plugged in, so make sure to change those settings accordingly.\\
+\\
+Once you complete these steps, Windows 10 will no longer power off USB devices connected to your computer, which can fix any problem you may have as a result of this feature.\\
+\\
+* Method 11: Disable and Enable USB ports in the bios.\\
+Restart your computer and enter it's BIOS, how to do this can be find in the manual of your computer.\\
+**__Be carefull to only change USB settings! Changing other settings can harm your computer!__**\\
+**__D&R is not responsible for changing the wrong settings!__**\\
+Be sure that you have a Keyboard and or Mouse that is connected to a different port then the USB.\\
+Now Disable the USB functionality and reboot your computer to let your Operating System detect the new setting.\\
+When the system is booted restart your computer again and enter it's BIOS.\\
+Now Enable the USB functionality and reboot your computer to let your Operating System detect the new setting.\\
+* Method 12: Updating the BIOS.\\
+**__KEEP IN MIND TO ONLY DO A BIOS UPDATE WHEN YOU KNOW THE RISK!__**\\
+**__A FAILED BIOS UPDATE BY FOR EXAMPLE A POWER FAILURE CAN CAUSE THE COMPUTER TO NOT OPERATE!__**\\
+In some situations a BIOS update can solve USB issues, these issues will be known by the manufacturers of your computer or mainboard.\\
+Before doing an BIOS update get informed about if there are issues with your system and the possible fixes.\\
