I had something similar but bought from Deal Extreme (dx.com). No driver available in Windows 8. I looked for the device number of the device without a driver in windows device manager and found the actual chip to be a 2775 or something like that. Then I found the site of the IC decoder and downloaded the generic driver from there. Works perfectly.
If you can find what is the device number of your USB device, I could check if it is the same as mine.
(if you still need this).
