2.4 Ghz wireless keyboard mouse driver not found (Penguin mouse)

[rvsw]

I got a wireless mouse Penguin Ambidextrous Vertical Mouse | Posturite. It is supposed to use generic windows 2.4 Ghz adapter. However, windows 7 is unable to find any drivers. The screenshot of device manager is appended. I tried various other ways e.g. take out other USB devices, reboot etc. I tried sfc /scannow . But the error persists. There is no usb.inf file in the C:\Windows . It works in Windows 8 machine but not in windows 7. other 2.4 Ghz mice work. The manufacturer says that they don't provide the drivers because the mouse uses generic drivers
Please advise what can be done.

Did you do a Search of the Windows Folder including subFolders and hidden Files? My Win7Ult has several such files but only 2 that are usb.inf only in subFolders of Windows, others have longer names but most appear to be associated with my AMD CPU/Gigabyte Motherboard setup.

I also tried sfc /scannow. It did not help
