  • Can you look at you device manager through your windows control panel and make sure the controller shows up when you plug it in under your usb list? If it shows up with a error message right click it and choose "Update Driver Software." Then choose "Browse my computer for driver software" and search for driver software in this location: "C:\" (or on whatever drive you have Windows installed).
    Make sure "Include subfolders" is checked and click next. Now windows will find a driver that is not digitally assigned right. Click "Continue Anyway" and Windows will install the driver. If you can not get going this way we will have to repair you windows drivers as the controller runs off of them.

    • If you have logitech drivers get rid of them as they may give other usb devices trouble. Here's the logitech work around to see if that's your issue.

      Disconnect your Logitech camera from your computer.

      Connect the USB Audio or MIDI device which is not working correctly.
      Select the Start menu at the bottom-right of your screen.
      Choose Control Panel.
      In the window that opens, double-click the control panel titled System. If there is no item titled System listed in the Control Panels window, click the link in the upper-left of the window titled Classic View. The System Control Panel should now be visible to the right. Double-click it to open the System Properties window.
      At the top of the Control Panel > System window that opens, click the tab titled Hardware.
      Then in the upper-left of the window, under Tasks, click the link labeled Device manager. You will be presented with a list of all the components installed on your computer.
      Right+Click the device titled USB Audio Device and select Properties
      In the window that opens, select the Driver tab.
      Click the button labeled Driver Details.
      You should see a list of the following 5 drivers:

      C:\WINDOWS\system32\drivers\drmk.sys
      C:\WINDOWS\system32\drivers\portcls.sys
      C:\WINDOWS\system32\drivers\USBAUDIO.sys
      C:\WINDOWS\system32\SysFxUI.dll
      C:\WINDOWS\system32\WMALFXGFXDSP.dll

      If there are more than 5 items in your own list, find out which one is not in the above list, click on it once, and write down it's name, location and any other information displayed. If this driver appears to be a Logitech driver, then your system is exhibiting the conflict covered here. To remove the Logitech driver, proceed with the instructions below:

      Navigate to the Logitech driver's location which you wrote down (see above). On most computers, it is located in the following directory:

      C:\WINDOWS\system32\drivers\
      Note: This may differ on different computers, or with different Logitech cameras.

      Locate the file whose name exactly matches the one you wrote down earlier.
      Your search will be easier if you select Details from the View menu at the top of the window.
      Right+Click the file and choose Delete.
      You will be asked if you are sure you want to delete the file. Choose Yes
      Restart your computer.

      Your USB Audio or MIDI device should now be properly recognized by your software.

  • Hello thanks for the help above - unfortunately it didn't work. I have those 5 drivers and no more listed in device manager in driver details. My Q49 is under "Sound, video and game controllers" but my keyboard still doesn't work.
    For some reason I have "NVIDIA High Definition Audio" listed 4 times under "Sound, video and game controllers" and "Realtek High Definition Audio" listed as well. All in all 6 things listed there. Do you think there might be a driver conflict or something?

    P.s I am also running Windows 7 (Professional) 64 bit.
    PC specs: Quad Core 2.0GHz, 4GB RAM, Nvidia GT240 512mb.

  • Any of: Albeton Live Lite Alesis edition, Red Dot Forever (very basic midi program).
    I've managed to get it working on XP Mode (Virtual PC) but it's laggy and it would be better on my proper computer.
