FX5051 w/ USB on WIndows 7 Home not Working

Altec lansing Fx5051 speaker system

Specs: Windows 7 Home Premium, i7/6

I have an Altec Lansing 5.1 FX5051 USB speaker system. No matter what I do I can only get maybe 4 of the 6 speakers working, sometimes only 3. I recently acquired a high-end i7 Laptop and its audio out is really only for headphones, so I need to use USB. I thought I can use this speaker system with USB. Prior to this I, I used to have a 5.1 Audigy 5,1 Sound card in my old P4HT system. So I know all the speakers do work.
So far;
.. Windows 7 sees the Altec Lansing FX5051 and it is the Default Sound Device.
.. AL's Properties/Enhancement = 'Speaker Fill' = Enable (Tried Disable All & Def w/ no affect)
.. Driver is Microsoft's USB Generic.
.. Sound / Communication is set to 'Do nothing'

Read a lot around the web with no clear solutions. Could use someone's help.

Thanks in Advance

Microsoft USB Generic is only stereo at best. If there were drivers supplied install them propely.

The system is a bit old and does not have Win 7 drivers.

Thank you for your input, but there never was a driver for the FX5051. It was a strict plug and play system as noted on the Altec L.., website. Windows 7 recognizes the speaker system no matter what USB port I use, but when I use Configure in Sound properties. I can only get some, but not all the speakers to fire off. Sometimes when I remove the USB and reconnect, it may be another set of speakers that are working. It seems like the Windows is stuck in some 3.1 mode.

The driver being installed is probably not compatible with Win 7. Ask the manufacturer for a solution.
